[RS6000] Don't pass -many to the assembler

[Sebastian Huber]

Hello,

I am sorry to come back to this thread after such a long time. I 
recently noticed that one of RTEMS multilibs is broken (for whatever 
reason it didn't show up in my regular build):

/build/git-build/b-gcc-git-powerpc-rtems5/powerpc-rtems5/m8540/nof/libgcc 
(master) > make
# If this is the top-level multilib, build all the other
# multilibs.

The assembler is called via:

/build/git-build/b-gcc-git-powerpc-rtems5/./gcc/as --gdwarf2 -I 
/home/EB/sebastian_h/archive/gcc-git/libgcc/../newlib/libc/sys/rtems/include 
-I . -I . -I ../../../.././gcc -I 
/home/EB/sebastian_h/archive/gcc-git/libgcc -I 
/home/EB/sebastian_h/archive/gcc-git/libgcc/. -I 
/home/EB/sebastian_h/archive/gcc-git/libgcc/../gcc -I 
/home/EB/sebastian_h/archive/gcc-git/libgcc/../include -a32 -me500 -mbig 
-o crtsavfpr_s.o /tmp/cc6Fy8nn.s

The e500 has no standard FPU. For this reason the multilib flags are: 
-mcpu=8540 -msoft-float

What do you think about the attached patch?
