build: Replace seq for portability with GNU Make variant

Some hosts like AIX don't have seq command, this patch replaces it
with something that uses just GNU make features we've been using
for this already before for the parallel make check.

2023-05-06  Jakub Jelinek  <jakub@redhat.com>

	* Makefile.in (check_p_numbers): Rename to one_to_9999, move
	earlier with helper variables also renamed.
	(MATCH_SPLUT_SEQ): Use $(wordlist 1,$(NUM_MATCH_SPLITS),$(one_to_9999))
	instead of $(shell seq 1 $(NUM_MATCH_SPLITS)).
	(check_p_subdirs): Use $(one_to_9999) instead of $(check_p_numbers).
