buildgcc: Remove all bashisms, making the script run also on BSD

Use sed instead of ${variable:start:length} and ${#variable}
    Use single = in string comparisons
    Use `eval echo '$'$variable` instead of ${!variable}
    Use > file 2>&1 instead of &> file
    Use readlink -f to expand the path of GCC configure
