mklibs: remove support

The support for mklibs has been marked broken since more than a year
and nobody cared to bring it up to a working state.

-# HOW IT WORKS
-#
-# - Gather all unresolved symbols and libraries needed by the programs
-#   and reduced libraries
-# - Gather all symbols provided by the already reduced libraries
-#   (none on the first pass)
-# - If all symbols are provided we are done
-# - go through all libraries and remember what symbols they provide
-# - go through all unresolved/needed symbols and mark them as used
-# - for each library:
-#   - find pic file (if not present copy and strip the so)
-#   - compile in only used symbols
-#   - strip
-# - back to the top
