    toolchain: gdb: Update to version 11.1
    
    The removed patch was already applied upstream.
    
    gdb now mandatory depends on gmp, tell configure where to find it
    explicitly. We already build gmp in the tools directory for gcc. Also
    make it use mpfr and mpc as we also build both of them.
