Cross-compilation fixes:

 - GCC >4.9:
     Newer toolchains trigger more warnings, which by default are
   treated as errors. Disable this while building the tools as this
   will be a recurring problem in the future.

   close Stichting-MINIX-Research-Foundation#105

 - FreeBSD: Fix some fetch.sh scripts which fails as FreeBSD's patch
   fails to patch two .info files. We ignore this for the time being.
