recordmcount.pl: fix typo in s390 mcount regex
commit4eb1782eaa
upstream. Commit85bf17b28f
("recordmcount.pl: look for jgnop instruction as well as bcrl on s390") added a new alternative mnemonic for the existing brcl instruction. This is required for the combination old gcc version (pre 9.0) and binutils since version 2.37. However at the same time this commit introduced a typo, replacing brcl with bcrl. As a result no mcount locations are detected anymore with old gcc versions (pre 9.0) and binutils before version 2.37. Fix this by using the correct mnemonic again.
