mmix-knuth-mmixware is a NO_DOT_IN_LABEL target, so it gets a "_"
instead of the "." in the identifier of interest. Also tested and
compared to the output for cris-elf which is "regular" regarding
labels: there are no "false positive" identifiers there. The "." in a
TCL bracket expression matches only a literal ".".
Committed as obvious.
gcc/testsuite:
* gcc.dg/no_profile_instrument_function-attr-1.c: Adjust scanned
regex for NO_DOT_IN_LABEL.
