    ada: Always use -gnatg in run-time GPR files
    
    This patch makes it so -gnatg is always passed to the compiler when
    rebuilding the run-time library with the dedicated GPR files. Before
    this patch, if a user rebuilt the run-time with -XADAFLAGS=XXX where
    XXX didn't include "-gnatg", the build would immediately fail. This
    case occurs when following the instructions in libada.gpr, which
    use '-XADAFLAGS="-gnatn"'.
    
    gcc/ada/
    
            * libgnat/libgnat_common.gpr: Unconditionally pass -gnatg.
