A patch for linux/mips libgcc

This patch is against gcc 2.86-85. But it is trivial to convert it for
gcc 3.0. The problem is
# gcc gcc/testsuite/gcc.c-torture/execute/ieee/fp-cmp-4.c -w -O0 -ffloat-store -lm
/tmp/ccaUWHSO.o: In function `test_isunordered':
gcc/testsuite/gcc.c-torture/execute/ieee/fp-cmp-4.c(.text+0x44): undefined reference to `__unorddf2'
I copied it from IRIX 6.
