A patch for linux/mips libgcc

["H . J . Lu" <hjl@lucon.org>]

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.
