[Bug target/39105] New: Warning about unused libgcc.a when using SGI linker

[J dot J dot vanderHeijden at gmail dot com]

Compiling the the most trivial program with GCC (using the SGI linker) results
in warnings :

$ gcc -o hello hello.c
ld: WARNING 84: /usr/local/gnu/lib/gcc/mips-sgi-irix5.3/4.3.3/libgcc.a is not
used for resolving any symbol.
ld: WARNING 84: /usr/local/gnu/lib/gcc/mips-sgi-irix5.3/4.3.3/libgcc.a is not
used for resolving any symbol.
ld: WARNING 84: /usr/local/gnu/lib/gcc/mips-sgi-irix5.3/4.3.3/libgcc_eh.a is
not used for resolving any symbol.

In IRIX6, this is prevented by setting the linker option '-dont_warn_unused'
before linking libgcc, and unsetting it again afterward.

Fix unnecessary wanings about libgcc.a from SGI linker

This trivial patch assumes the patch for PR39104 has also been applied, but
they are otherwise unrelated.
