joel's tc-mips.c patch :(

[Joel Sherrill <joel@OARcorp.com>]

Well it must not be right.  It did not complete the multilib build.  I had
ben using the gas-971208 snapshot internally and compared the tc-mips.c
file against the version in that snapshot.  It appears that a chunk of
code disappeared.  A new version of the patch is below my signature which
should give a hint as to what got accidentally deleted.  It is still not
right though but it gets farther.  

Here is where it got to.

  /usr2/tools/build-mips64orion-tools/gcc/xgcc
-B/usr2/tools/build-mips64orion-tools/gcc/ -O2  -DCROSS_COMPILE -DIN_GCC
-O2 -I./include  -G 0 -g1 -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED
-fexceptions -Dinhibit_libc   -I. -I../../src/gcc -I../../src/gcc/config

  if [ $? -eq 0 ] ; then true; else exit 1; fi; \
  /usr2/tools/build-mips64orion-tools/binutils/ar rc tmplibgcc2.a
${name}.o; \
  rm -f ${name}.o; \
done

/tmp/cca15880.s:439: Internal error!
Assertion failure in macro_build at ../../src/gas/config/tc-mips.c line
2351.

Suggestions appreciated.  I really do not know enough about the mips to
fix this one right.
