With these adjustments, cached object files can now be shared across
multiple Android trees on a single workstation:
* Compiler binary modification time no longer causes cache misses,
as a hash of the compiler binary is taken rather than looking
at the mtime and size
* Header file modification time no longer causes cache misses,
the headers are now always hashed
* Macros such as __DATE__ and __TIME__ no longer cause cache misses
* All paths in preprocessed source (due to use of -g) are now relative
These options require ccache 3.1 or later to be used; ccache 2.4 will
ignore these.

Bug: 6754632
So the warning won't show up when you run lunch.
Now the warning only shows when you do a clean build.

Recover variable build_mac_version which is removed on
commit 644dc16 and added on commit 9ce06f1.
Without this, ranlib libSDL.a is executed on Lion which
causes build fail of emulator-arm.

XCode 4.3 and later use a different location for SDKs. This check in
ensures the build checks for the new location as well as the old one.

Change TARGET_ARCH_VARIANT from x86-atom to x86, for the reason
that atom-specific instruciton like "movbe" isn't "generic" to
x86 Android devices and x86 host running emulator-x86, which may
crash non-atom host in VT because "movbe" isn't supported natively.
Also revert previous fix in TARGET_linux-x86.mk which conservatively
disable "movbe" across the board

Intruction "movbe" (move data after swapping bytes) is only available in
Intel atom. Disable it for more general x86 devices and x86 hosts which
run emulator-x86. Although emulator-x86 can support "movbe", most of
the time we want to run emulator-x86 with VT support for speed (with KVM
in Linux, or HAXM in Windows/MacOSX). The presence of "movbe" can crash
emulator-x86 in VT because non-atom host doesn't have it natively.

Added Mountain Lion to the list of versions which don't need ranlib
and don't need the pre-Lion linker flags

The cc and c++ compilers included in Apple's command line tools show some
unusual behaviour which causes the build to fail in several projects under
Xcode 4.3
This patch uses the gnu compatibility gcc and g++ compilers on OS X instead
to reduce problems, and generates an error when an llvm based compiler is
detected because they currently do not generate usable emulator executables
due to them not honouring global register variables.

Enable relro / bind_now when compiling Android applications.
This marks certain regions of memory as read-only after linking,
making memory corruption security vulnerabilities are harder
to exploit.
See:

Stop using the custom linker script, which inhibits
relro / bind_now support.
