Greg Stein a13d856e8f * Switch to a single, top-level Makefile (simplification, consistency)
* use libtool to compile/link all programs
* remove */Makefile.in and remove them from configure
* remove autom4te.cache after running autoconf
* remove .o from the FILEMAP logic in configure and the Make system;
  provides more flexibility in the Makefile to use it
* for VPATH builds: create the build subdirs by running
  "make mkdir-init" from the configure script
* adjust .cvsignore files to account for presence of .libs now
