Report on ML, as usual :)

This is no correct fix.  The problem was that configure script didn't
set BUILD_MODULES conditional.  It seems due to lack of quotes.  It
used to work with the older automake, but it no longer does.

This is another problem.  simple_abst.c shouldn't be built with no
libdl is available.

Both issues are fixed now in git tree.
