Fix full paths stored in binaries

[alexey-lysiuk]

A few libraries and tools have full paths to build or install directories saved inside them.

• glib/lib/libglib-2.0.a
• gmake/bin/gmake, doesn't affect built GZDoom/Raze executable
• instpatch/lib/libinstpatch-1.0.a
• intl/lib/libintl.a
  Configure with --localedir=/usr/local/share/locale
  Install with make install-exec-am install-nodist_includeHEADERS
• pkg-config/bin/pkg-config.exe, doesn't affect built GZDoom/Raze executable
• vpx/lib/libvpx.a, doesn't affect built GZDoom/Raze executable
• vorbis/lib/libvorbis.a, vorbis/lib/libvorbisenc.a, vorbis/lib/libvorbisfile.a
