The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and this was starting to cause some tools heartburn. It also made "make V=1" almost useless, since trying to following the individual commands run by make was lost in the noise of all of the defines. So fix this by putting the configure-generated defines in lib/config.h and the directory pathnames to lib/dirpaths.h. In addition, clean up some vestigal defines in configure.in and in the Makefiles to further shorten the cc command lines. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
