I think I've found the source of this, to summarize: during RTL expand
(yes during *expand*), .global __aeabi_* directives are added to the asm
output when seeing use of the libcalls. Later the calls get optimized
out in some way, leaving the unused .global symbols...

I would think that, under an EABI toolchain environment, all the AAPCS
defined __aeabi_* runtime functions should always be available (e.g.
libgcc)  Thus we should be able to skip adding these .global __aeabi_*
directives completely? Ramana?
