Build log

Recently the git master for wayland stopped building with pthread-related
errors:

../src/.libs/libwayland-server.so: error: undefined reference to
'pthread_key_create'
../src/.libs/libwayland-server.so: error: undefined reference to
'pthread_getspecific'
../src/.libs/libwayland-server.so: error: undefined reference to 'pthread_once'
../src/.libs/libwayland-server.so: error: undefined reference to
'pthread_setspecific'

Looking at the build system, I think it is completely missing the code
necessary to detect and set proper flags for pthread support. As suspected,
passing 'LIBS=-pthread' to configure results in the build succeeding.

Attaching our build log.
