A patch for linux/mips libgcc

Subject: 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.

        * config/mips/t-linux: New.

        * configure.in: Add mips/t-linux to tmake_file.
