BUILD: Makefile: allow external makefiles to provide build targets

Let EXTRA_MAKE fragments set EXTRA_TARGET_BUILD to a nonempty value to
provide their own build and cleanup targets instead of building HAProxy.
Keep the common option handling and regression-test targets available.

Evaluate the selector after global compiler and linker options have been
initialized so a fragment can install its alternate build rules there.
