There were differences between linux gcc, android gcc,
MacOS clang, and 32 vs. 64-bit w.r.t the __builtin
functions for detecting arithmetic overflow. I couldn't get
them all working at the same time. Instead, I removed them,
and changed to always use the inline assembly. This works
in all the configurations above.
This change also adds a simdbc64 target for building simdbc
for 64-bit, and sets up the android targets. simdbc targets
arm, and simdbc64 targets arm64. You can build them with:
$ ./tools/build.py -m release -a simdbc{64} --os=android runtime

This change also avoids the need to
do another 'gclient runhooks' when switching
between Android and Linux builds, and between
IA32 and ARM Android builds.
gyp does not allow 'libraries' sections inside of
configurations. Therefore, since some architecture
specific paths, libraries, etc. must be specified
on the Android NDK's linker command line, to avoid
re-gyping when switching between Android IA32 and ARM,
this change moves the architecture specific linker
flags to a script, android_link.py.
To avoid re-gyping when swtiching between Linux and
Android, this change creates new configurations
that specify the target OS as well as the the target
architecture, e.g. ReleaseLinuxARM or ReleaseAndroidARM
instead of ReleaseARM.
This change also adds a --toolchain flag to build.py,
and removes obsoleted logic for setting up the Android
build.
