# Build in Release mode: pahole's CMakeLists defaults to Debug, which adds
# -Werror (and -O0). glibc 2.43 in forky makes strchr()/bsearch() and
# friends preserve the constness of their argument, so pahole's assignments
# of their results to non-const pointers now trip -Wdiscarded-qualifiers and
# fail the build. Release drops -Werror and builds with -O2.
