    libgcc: Ensure that gcc configure options are passed to libgcc too
    
    libgcc uses certain options from EXTRA_OECONF as well, curently we are
    ignoring them, as a result we do not configure libgcc to match cross gcc
    in some cases e.g. ppc/musl should have used 64bit long doubles but
    it went for 128-ldbls which is default, works on glibc but not on musl
