[PATCH] Fix profile name files without -fprofile-dir.

[Martin Liška]

Hello.

As mentioned in here https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91971#c7,
we should not mangle profile data and note files unless -fprofile-dir is
used (and an absolute path is used).

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
I'll install the patch if there are no objections.

Thanks,
Martin
