that does the following:
Changes:
Remove $(SED) and $(CP) from make/custom/*.cfg
Motivation:
* autoconf and automake presuppose sed and cp to be present.
* make/host.cfg.in already contains SED = sed hard-coded into it for
a long time.
* Elimination of make-variables
* Eliminate make/*.cfg files or at least reduce their complexity :)
