From: Jan Kiszka <jan.kis...@siemens.com>
Not all (didn't find any) mingw32 cross-toolchains ship a binutils-devel
package, thus lack libiberty.a. According to 08f3896a, -liberty is only
needed for getopt when building for 64 bit. Test for the availability
of a getopt implementation and only pull in libiberty when linking
without it failed.
