Recognize the arm-linux-androideabi "triplet". (Actually I doubt that
is a well-formed triplet at all, what are the Google people smoking?)

Allow longer lines in pkgdata.cpp as the compiler command line gets
quite long for cross-compilation to Android.

Add the proper assembly source file format for Android to pkg_genc.c
and use that.

Probably a good idea to use --disable-dyload on Android (and iOS).

Tweak gcc flags used for Android a bit to work around some Android C
header weirdness related to strictness and 64-bit types.
