build: some refactorings in cfg.mk

Browse Source 
Partly a minor cleanup, partly a preparation for future changes.

* Makefile.am (all_programs): Rename ...
(all-progs-but-lbracket): ... like this, and re-define it to expand
at make time rather than only at recipe time (i.e., using $(shell ...)
instead of `...`).
(check-programs-vs-x): Adjust.
