Presence of *.a doesn't serve anything for -static building
(just occuping disk space and hiding some errors in package configure

Well, unfortunately libtool didn't change its mind and uses
dependency_libs during shared linking too.
Maybe this is the only thing that should be changed...

Packaging *.la in -static has several faults:

- content of new .la file depends on presence of *.la files from
  dependent libraries, so the rule on their precence on builders must be

- we can't forbid installing _any_ static library on builders - in some
  rare cases they are used.

- we don't want to install all *-static on builders from the reasons
  mentioned above.

Plus: keeping all *-static containing *.la files on builders is in no
way better than preevailing situation: *.la files are still "poisoned"
by obsolete libraries (and thus rebuilding would be still required
in case of transition like libpng12 -> libpng14 or dropping some
dependency), and they affect on shared library building (-as-needed
still needs to be enforced).
