The CL #35139 (https://codereview.chromium.org/1775323002) added V8_TARGET_ARCH_IA32 macro in src/globals.h. X87 is almost same as IA32, So It needs the V8_TARGET_ARCH_X87 macro in src/globals.h too.

Fixes for misnamed toolchain from https://github.com/appcelerator/v8_titanium. Added a way to specify the NDK path since the Mac versions of the NDK aren't checked into the tools repo. Disabled a few dependencies which do not build on the Mac but which aren't needed for building usable V8 static libraries. Made the including of libdl and librt omitted for Mac hosted builds.

Despite man page documentation: -f Display the symbol table of a dynamic library flat (as one file not separate modules). `nm` on mac treats `-f` as a shorthand for `-format`. The `-f` argument does not seem to be required, so just remove it completely. (For `-format` documentation - see `nm --help` on mac).

Check if a previous run left an inconsistent state behind. The check is right before trying to push a new state as then all information is available, like commit message and tag name. This is still only a band-aid. If gnumbd is down for a longer period, an unprocessed commit won't be found, but the push attempt will still fail.

This patch replaces the unused 'take_snapshot' parameter on FatalProcessOutOfMemory() with a 'is_heap_oom' parameter. The parameter is set to true on error paths where the JS heap is out of memory, as distinct from a malloc() failure i.e. process out of memory. The message output to stderr or passed to embedding applications via FatalErrorCallback is 'Javascript heap out of memory' rather than 'process out of memory'.
