We used to do that unconditionally but that caused lots of spurious
warnings in gcc-4.4.x about an unrecognized gcc option.

This is used by debug tools to find symbols for the stripped binary.
Adds ~70 bytes to each DSO, ~25000 bytes total, which is about 0.01% of the
system image.
This change only affects -eng and -userdebug builds, and does not affect -user.

"lunch sdk-eng" on cygwin tries to use a gcc.exe from the
prebuild arm toolchain, but it doesn't exist. This prevents
from setting variables to point on a gcc toolchain if there
is none for the given arch.

Set LOCAL_GROUP_STATIC_LIBRARIES := true to group the static libraries,
in case we need gcc flags "-Wl,--start-group" and "-Wl,--end-group" to
fix circular references.

Option --strip-all will remove the static symbol section in addition to debug
symbols. We do not need the static symbol table in libraries installed on the
target.

This patch removes support for prelinking from the build system. By now, the
prelinker has outlived its usefulness for several reasons. Firstly, the
speedup that it afforded in the early days of Android is now nullified by the
speed of hardware, as well as by the presence of Zygote. Secondly, the space
savings that come with prelinking (measued at 17MB on a recent honeycomb
stingray build) are no longer important either. Thirdly, prelinking reduces
the effectiveness of Address-Space-Layout Randomization. Finally, since it is
not part of the gcc suite, the prelinker needs to be maintained separately.
The patch deletes apriori, soslim, lsd, isprelinked, and iself from the source
tree. It also removes the prelink map.
LOCAL_PRELINK_MODULE becomes a no-op. Individual Android.mk will get cleaned
separately. Support for prelinking will have to be removed from the recovery
code and from the dynamic loader as well.

Added LOCAL_NO_CRT to enable building executables that do not link
to the C runtime library.
Removed support for LOCAL_MODULE_SUBDIR since it was broken
and unused. (Was going to use it but ended up using LOCAL_MODULE_PATH
instead.)

The purpose of removing global inline options is to give
compiler the opportunity to do inline optimizations and inline
tunings for Android native codes.
By removing these global inline options now, the size of
almost all native libraries are reduced. And there is no
noticable performance degradation on webkit, gcstone and
skia benchmarks.

androideabi target is already in upstream GCC. The arm-linux-
androideabi toolchain can be built directly from upstream GCC.
Switching from old special tailored arm-eabi toolchain to the new
arm-linux-androideabi toolchain make us closer to the opensource
community and friendly to all toolchain developers.
kernel still uses arm-eabi toolchain. So we add arm-eabi toolchain
path to PATH.
The arm-linux-androideabi-4.4.x toolchain is built with the same
source as the latest arm-eabi-4.4.3 toolchain except for the
target change patches.

between libc, libc_nomalloc and libgcc. When building with upcoming
arm-linux-androideabi toolchain, Symbol raise is needed by libgcc.a
and defined by libc.a or libc_nomalloc.a.which.
This patch groups libgc.a, libc_nomalloc.a and libgcc.a together, which is
a minimal group to solve this problem.

gcc-4.4.3 toolchain is based on fsf GCC-4.4.3 with numerous patches.
It reduces 3.65% code size than the prebuilt gcc-4.4.0 toolchain,
and improves 3.4% performance on Android benchmarks.
The toolchain uses gold as default linker. With gold, the toolchain
further reduces 1MB system image.

Add -Wa,--noexecstack and -Wl,-z,noexecstack as default
flags when compiling applications. This enables NX
protections, which prevent code from executing on the
stack or heap. NX protections can block a large number
of buffer overflow attacks, and is an important security
feature.

A package can define a LOCAL_LDFLAGS. If a LOCAL_LDFLAGS
exists, it should come after the global LDFLAGS, to allow
the local flags to override the global flags.

The only OS-ARCH combo that would have benefited from it
is linux-x86, but it explicitly used separate configurations
for the HOST_ and TARGET_ side of things.
This makes is clear which files are related to the HOST_
configuration and which ones are related to the TARGET_
configuration, and expands $(combo_target) to the only
possible/reasonable value that it could have had in every
file.
This also cleans up the simulator, by moving it in a single
place in TARGET_linux_x86 (since the only part that's special
is to use HOST_ settings even when building TARGET_ modules).
