    driver: fix -gz=none error message with missing zstd
    
    We wrongly report:
    
    $ echo "int main () {}" | gcc -xc -gz=none -
    gcc: error: -gz=zstd is not supported in this configuration
    
    if zstd compression is not supported by binutils. We should emit the
    error message only if -gz=zstd.
    
            PR driver/108572
    
    gcc/ChangeLog:
    
            * gcc.cc (LINK_COMPRESS_DEBUG_SPEC): Report error only for
            -gz=zstd.
