-flto tests don't pick up libgloss code at link time

[Anthony Green]

All of the -flto tests fail for moxie-elf...

http://gcc.gnu.org/ml/gcc-testresults/2011-03/msg00399.html
It turns out that this is because it fails to link with the code in 
libgloss when I enable -flto.

I link the test code with a special linker script (sim.ld) that pulls in 
the libgloss code found in the moxie libgloss port's libsim.a. 
Unfortunately it looks like this just doesn't happen with -flto.  Any 
ideas why?

Thanks,

AG
