Speed up bootstrap by improving lt_combine.

Browse Source 
* libltdl/m4/ltsugar.m4 (lt_combine): Mirror Autoconf 2.62
improvements.  Includes a semantic change where the separator can
now be empty, and where an empty fourth argument is now treated as
a valid suffix.
* libltdl/m4/libtool.m4 (_lt_decl_varnames_tagged): Adjust to new
semantics of lt_combine.
(lt_decl_varnames_tagged): Fix quoting and optimize.

Kill _LT_LIBSOURCES; it wasn't checking anything useful.
* libltdl/m4/ltdl.m4 (_LT_LIBSOURCES): Delete.
(LTDL_INIT): Ignore arguments to AC_LIBSOURCES during _LTDL_SETUP,
