The new tests fail on darwin:
/opt/gcc/work/gcc/testsuite/gcc.target/i386/nop-mcount.c:1:0: error:
-mnop-mcount is not implemented for -fPIC
and gcc.target/i386/record-mcount.c fails because mcount_loc is not found in
the assembly.

The Linux kernel dynamically patches in __fentry__ calls in and
out at runtime. This allows using function tracing for debugging
in production kernels without (significant) performance penalty.
For this it needs a table pointing to each __fentry__ call.
The way it is currently
