Allow dynamic-object dependencies and build flags to be specified as distinct from

DYNOBJ_LOADER_PROG instead of SHLIB_EXPFLAGS and a hardcoded pathname to the KDC binary,
respectively.
* config/pre.in (DYNOBJ_EXPDEPS, DYNOBJ_EXPFLAGS): New variables.
* config/libnover.in ($(LIBBASE)$(DYNOBJEXT)): Use DYNOBJ_EXPDEPS instead of SHLIB_EXPDEPS
in dependencies.
* aclocal.m4 (KRB5_BUILD_LIBRARY_WITH_DEPS): Substitute DYNOBJ_EXPDEPS and DYNOBJ_EXPFLAGS.
* modules/kdb/db2/Makefile.in (DYNOBJ_LOADER_PROG, DYNOBJ_EXPFLAGS_WITH_LOADER,
DYNOBJ_EXPDEPS_WITH_LOADER): New variables.
