[libc] Clean up skipped and failing cmake (#115400)
I normally run my cmake with LIBC_CMAKE_VERBOSE_LOGGING set to ON so I
can debug build issues more easily. One of the effects of this is I see
which tests/entrypoints are skipped on my machine. This patch fixes up
the tests and entrypoints that were skipped, but easily fixed. These
were:
libc.src.pthread.pthread_spin_destroy
libc.src.pthread.pthread_spin_init
libc.src.pthread.pthread_spin_lock
libc.src.pthread.pthread_spin_trylock
libc.src.pthread.pthread_spin_unlock
(entrypoints were just missing)
libc.src.wchar.btowc
(I forgot to finish it)
libc.test.src.sys.statvfs.linux.statvfs_test
libc.test.src.sys.statvfs.linux.fstatvfs_test
(Incorrect includes for rmdir, needed some cleanup)
libc.test.integration.src.unistd.execve_test
(wrong dep for errno)
libc.test.src.math.smoke.fmaf_test
(add_fp_unittest doesn't support flags)
libc.test.src.stdio.scanf_core.converter_test
(needed to be moved away from string_reader, further cleanup needed)
