This build option has been deprecated since 8.0.
Remove all CONFIG_GPROF code that depends on that,
including one errant check using TARGET_GPROF.

-The ``--enable-gprof`` configure setting relies on compiler
-instrumentation to gather its data which can distort the generated
-profile. As other non-instrumenting tools are available that give a
-more holistic view of the system with non-instrumented binaries we are
-deprecating the build option and no longer defend it in CI. The
