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

# get the right flags, checking first for -lpthreads, then -lpthread, and lastly

# 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.

#

# The following CMake variable only disables the TRY_RUN call in the -pthread

# test.
