From: Jerome Marchand <jmarchan@xxxxxxxxxx> 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.
