- eliminate ambiguities between GNU-ish and SysV-ish make flavors;
- switch [back] to -e;
- fold/unify rules;

This is follow-up to the patch introducing common BUILDENV. Idea is
to collect as much parameters in $(TOP) as possible and "strip" lower
Makefiles for most variables [and thus makes them more readable].

dynamic loading is consistent with respect to engine ids.

[most importantly] put back dependencies accidentaly eliminated in
check-in #13342.

during "make errors" and thus during "make update".

Fix lots of bugs that util/ck_errf.pl can detect automatically.
Various others of these are still left to fix; that's why
"make update" will complain loudly when run now.

install to a different location than it had created. (BTW, VMS will need a
matching fix in eng_list.c.) Note, these aren't ssl-specific, so I'm
putting "engines/" into the libs directory rather than at the "--prefix"
level or inside "ssl/".

think that proper Makefile clean-up is required.
