    build-system/gnu: strip with --strip-unneeded
    
    Apart from debug information, one can also strip some symbols. This can
    be a significant difference, qtbase:out consists of about 5 MB of those
    symbols. As per [1], --strip-debug is included in --strip-unneeded, and
    the debug files created also contain a copy of the information removed
    by --strip-unneeded.
    
    Linux From Scratch suggests that this option shouldn't be used on static
    libraries [2], however other sources [3] indicate otherwise. Building a
    toolchain with this patch succeeds, and the result works fine for
    'gcc -static hello-world.c'.
