make install-cross broken

there's an issue with gdb-2013.05/sim/arm/armsupp.c:639.
I believe it should 'return result;' instead of 'return;'

I presume this is with clang or not otherwise specifying a compiler on a recent version of X-Code on OS X?

If I recall this is the main thing that clang complains about. I agree that your approach makes sense, I'm not sure why this has remained unchanged in upstream for years now.
