We can save some space for platform build with this.
Previously an extra libgcc.a was put before libc.so so libraries built
against new platform can run on old platforms. This is needed only for
unbundled build.

Mac's linker doesn't support --start-group and --end-group; it scans
libraries repeatedly even without these options, so it's not necessary.

Make the host and the target x86 build more uniform by using the same machine flags.
Its unlikely Android has ever been built on a machine without SSE3 support.

Add -D_FORTIFY_SOURCE=1 to the default cflags
Update build rule for executable with PRIVATE_ALL_WHOLE_STATIC_LIBRARIES
Use single dash version of -print-whatever
compile everything with relro / bind_now
Enable NX protections
Some other cleanups to reduce differences between ARM and MIPS config files

For the current MIPS compiler __builtin___clear_cache() generates synci instruction only with -msynci option So, add -msynci to all mips32r2 makefiles. Also add msynci to the list flags not recognized by clang.

Error "cc1plus: error: unrecognized command line option
‘-mfloat-abi=softfp’" is much more confusing than
"...gcc: No such file or directory".
Also we don't build in Windows/Cygwin any more so we don't need the old
trick.

Otherwise the previously exported value will be sticky and the value
defined in the TARGET makefile is ignored.

Enable FORTIFY_SOURCE for Android x86. This adds certain security
protections to Android programs, checking for common programming
mistakes and buffer overflows.
FORTIFY_SOURCE protections have been enabled for ARM since

1. Use prebuilts/gcc/darwin-x86/host/i686-apple-darwin-4.2.1
See https://android-review.googlesource.com/#/c/46223/
2. Rewrite logic dealing with mac_sdk_version to support all
MacOSX SDK 10.6, 10.7 and 10.8. Note that since
ad2342375963c2468849c1f83a97158383db6511 emulator no longer
depends on 10.6 to build. Since the lowest SDK among intersection
of the "available" and the "supported" SDKs is picked, add a
new variable MAC_SDK_VERSION for developer really want to overwrite
it. MAC_SDK_VERSION still has to be one of the supported, though.
3. Improve mac_sdk_path detection to deal with case where Xcode
*dmg is mounted only, not installed at /Applications.
4. Now we can retire BUILD_MAC_SDK_EXPERIMENTAL

Emit a warning when the static linker detects a shared library
has text relocations. Text relocations make it harder to
share pages across processes, and make it harder to use
certain memory protection features in, for example, SELinux.
This warning will turn into an error in a future change
(via --fatal-warnings)

Third time's the charm. :-)
In b238210c01, we added
-Wl,--warn-shared-textrel to TARGET_GLOBAL_LDFLAGS. This generated
a warning whenever we created a shared library with a text
relocation. At the time, we wrote:
=====

All code which uses text relocations has either been fixed, or
we've temporarily worked around the issue so the code can still
compile.
Enable --fatal-warnings.
This reverts commit 942167dab8.
