recordmcount.pl: look for jgnop instruction as well as bcrl on s390
commit 85bf17b28f97ca2749968d8786dc423db320d9c2 upstream.
On s390, recordmcount.pl is looking for "bcrl 0,<xxx>" instructions in
the objdump -d outpout. However since binutils 2.37, objdump -d
display "jgnop <xxx>" for the same instruction. Update the
mcount_regex so that it accepts both.
