build: Respect CFLAGS and LIBS env settings

Browse source 
The build system does not honor the flags set externally and replaces
it with the pthread-only flags when detecting pthread
availability. This breaks the configuration of cairo in some
cross-compilation environments:

conftest.c:1: note: someone does not honour COPTS correctly, passed 0 times

The test for pthread should append the new flags to the old one.
