# In case of static-lib-only builds, CMake's FindThreads.cmake code tries to

# for -pthread.
# The 2 first link checks fail because of undefined symbols: __libc_setup_tls.
# In the later check, CMake successfully compiles and links the test program,
# but it also tries to run it, which is wrong when cross-compiling.
