proposed fix v5 addendum (only partially tested)

I've only run check on RUNTESTFLAGS="ms-sysv.exp" so far and I have a full
regression test running right now, but I *think* this is correct.  I'm
presuming that using .hidden is a no-no as well, at least from what I can tell
it's elf-specific, but I'm not sure what else to do with it other than #ifdef
__ELF__.  (I googled 'hidden elf' and got a lot of interesting fiction...)  So
I'm sorry to just ask you to see if it blows up on Solaris & Darwin w/o gas.

I'm also unsure about my changes to libtgcc/config.host as I just don't have a
broad understanding of all of the *nix platforms out there.

Feedback greatly appreciated!

Thanks,
Daniel
