Additional source handling

src_postfetch()

    tar xf ${ANYSRCDIR}/mpfr-4.0.2.tar.xz
    mv mpfr-4.0.2 mpfr
    tar xf ${ANYSRCDIR}/gmp-6.2.0.tar.xz

Configuration

Add new rule to sed replacement:

    -e "s@/lib64@/lib@g" \

This is needed to set up the dynamic linker for use the single lib directory ./lib/ instead of both ./lib and ./lib64.

src_config()
{
    for file in gcc/config/{linux,i386/linux{,64}}.h
    do
        cp -u $file{,.orig}
        sed -e "s@/lib\(64\)\?\(32\)\?/ld@${PREFIX}&@g" \
            -e "s@/usr@${PREFIX}@g" \
            -e "s@/lib64@/lib@g" \
            $file.orig > $file
        echo "
    #undef STANDARD_STARTFILE_PREFIX_1
    #undef STANDARD_STARTFILE_PREFIX_2
    #define STANDARD_STARTFILE_PREFIX_1 \"${PREFIX}/lib/\"
    #define STANDARD_STARTFILE_PREFIX_2 \"\"" >> $file
        touch $file.orig
    done
