build-host-gcc.sh: --disable-plugins --disable-plugin globally
Until a GCC bug is fixed in plugin cross compilation, plugins
cannot be (canadian?) cross compiled:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50229
I checked the released NDK r8d and the plugins are not enabled
on any GCC (configure lines all contain --disable-plugin)
