Subject: fuzzing: Add -lm to LDFLAGS if the coverage sanitizer is used
X-Git-Tag: 5.7.2dr1~23
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6e55856830477bbd8283981d5d7f16bfd3a9222f;p=thirdparty%2Fstrongswan.git

fuzzing: Add -lm to LDFLAGS if the coverage sanitizer is used

libFuzzer apparently uses math functions (e.g. ceilf) for that sanitizer.
