* configure.in: Use AC_LIB_HAVE_LINKFLAGS instead of
AC_LIB_LINKFLAGS when checking for library functions.
* configure.in: Don't waste time checking for headers and
functions we know must be there. But manually AC_DEFINE the
functions that might be missing from non-Unix systems.

* configure.in: Don't check for strpbrk and mktime.
