When building with BR2_REPRODUCIBLE the toolchain wrapper passes
-fdebug-prefix-map for all packages that are built. But this doesn't
affect the target libraries (like libgcc) built by GCC's build system.
GCC 4.3 added a configure option to set the debug prefix map for these
libraries, which is used here to avoid encoding potentially
non-reproducible build paths into the debug data.
