    Disable PROFILE option by default

    Hardware based profiling (e.g. hwpmc) is much better and produces more
    useful results.  Today the profiling lib archives (_p.a) serve no real
    purpose other than increasing the library build time.

    Both upstream and base system (in commit b762974cf4b9) Clang have been
    modified to remove the special case for linking against these libraries.

    Clang's -pg support and mcount() remain, so building with -pg can still
    be used on code that the user builds; we just no longer provide prebuilt
    libraries compiled with -pg.

    Discussed on freebsd-hackers[1] / freebsd-current [2] in 2020 and
    freebsd-arch [3] in 2021.  A deprecation notice was added in
    commit 175841285e28.
