Patch to use the file from -Map as a target for --cref output.

The --cref option on ld.lld only seems to write to stdout, ignoring the
-Map=filename option. This is a change from GNU ld.

To reproduce, compile and link any code with --cref, for example:

    echo 'int main() { return 0; }' > test.c
    cc -Wl,-Map=test.map -Wl,--cref test.c

The cross reference table is emitted on stdout instead of being written to
test.map.

A patch (against the lld imported into the FreeBSD 12.2 tree) that resolves the
issue for me is attached.</pre>
