[Bug target/39694] New: -print-file-name doesn't work on mingw in 100%.

[pluto at agmk dot net]

on mingw target i can't get libgcc_s.a path.

the path to libgcc.a is returned correctly:

$ i686-pc-mingw32-gcc -print-file-name=libgcc.a
/local/devel/toolchain44/i686-pc-mingw32.host64/lib/gcc/i686-pc-mingw32/4.4.0/libgcc.a

but the libgcc_s.a case doesn't work. it returns:

$ i686-pc-mingw32-gcc -print-file-name=libgcc_s.a
libgcc_s.a

while file exists in /local/devel/toolchain44/i686-pc-mingw32.host64/lib/
another problem is to get libgcc_s-*.dll path. in this case:
/local/devel/toolchain44/i686-pc-mingw32.host64/bin/libgcc_s_dw2-1.dll

$ i686-pc-mingw32-gcc -v
Using built-in specs.
