Additional context

There is already a few tests excluded for failing, tests are run with:

CTEST_OUTPUT_ON_FAILURE=TRUE ctest --test-dir build -E "absl_str_format_convert_test|absl_mutex_test\
|absl_notification_test|absl_per_thread_sem_test|absl_sysinfo_test|absl_random_beta_distribution_test"

using

CXXFLAGS="$CXXFLAGS -flto=auto"

causes even more tests to fail: https://gitlab.alpinelinux.org/a16bitsysop/aports/-/jobs/824116

[a16bitsysop]

looks like this is to do with gcc 12, if I change to clang 14.0.6 the tests pass: https://gitlab.alpinelinux.org/a16bitsysop/aports/-/jobs/824948
