Update arch name used by the Android buildbot to reference "i386" rather
than "i686" since this is the only x86 library name post D26796 + D26764.
This is necessary so that the scripts push the correct library file.
Btw could you move this comment to line 72?
In fact, this might be wrong.
Ndk arch should be i686, unlike the standalone toolchain path.
FWICS ndk arch is actually 'x86' (the second argument). The first seems to be used only to construct the build directory path.
Sure, will do.
