FYI: weed out AM_CPPFLAGS

[Ralf Wildenhues]

Applied to HEAD and branch-2-0.  (we need `-I. -I$(srcdir)' because the
ltdl user might have put nostdinc as global Automake option.)

This broke compilation with Portland's pgcc.

Regards,
Ralf

        * libltdl/Makefile.am: $(builddir) is not defined, replace by `.'.
