Hi
Testing binutils and gcc heads, I am getting this error when
linking the autoconf probe for RTEMS when the CPU CFLAG
-mgcc-abi is used:
$ cat m.c
main()
{
}
[joel@rtbf64a test-gcc]$ v850-rtems4.11-gcc -mgcc-abi m.c

/users/joel/test-gcc/install-svn/lib/gcc/v850-rtems4.11/4.8.0/gcc-abi/libgcc.a
when searching for -lgcc
I don't have any patches to gcc or binutils.
Any suggestions on what to look for?

Well, libgcc_s is not of that arch which ld expects.

Well Doh!
The gcc-abi and 8byte multilib variants appeared to have
been added around 2012-11-20 by Nick Clifton. I think he
missed changing the ASM_SPEC in gcc/config/v850/rtems.h
when he added it. v850-rtems-gcc wasn't passing in the expected
cpu specification flags.
Nick.. how does this patch to gcc/config/v850/rtems.h look?

Perfect. Sorry about the snafu. I have checked the patch in along with
this changelog entry.
Cheers
