Subject: perf python: Make clang_has_option() work on Python 3
X-Git-Tag: v4.20-rc1~169^2~5^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e13a5d69c31d35538e80176d54d95b6addf4dcbf;p=thirdparty%2Flinux.git

perf python: Make clang_has_option() work on Python 3

Use a bytes literal so it works with Python 3's version of Popen().
Note that the b"..." syntax requires Python 2.6+.
