	assertion failure for certain invalid signatures. Based on a patch
	contributed by Daiki Ueno.

	* testsuite/rsa-pss-sign-tr-test.c (test_main): Add test case
	contributed by Daiki Ueno. Problem originally found by oss-fuzz,
	see https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2132.

	Rework the previous change, which had the unintended effect of
	always regenerating .test-rules.make after ./configure is run.
	* testsuite/Makefile.in (test-rules.stamp): New stamp file target,
	depend on Makefile.in, and run $(MAKE) test-rules.

	* testsuite/pss-test.c: Delete magic to let valgrind to check if
	pss_encode_mgf1 is side-channel silent with respect to the salt
	and digest inputs. It turns out that the most significant bits of
	the padded bignum, and hence its size, depends on these inputs.
	Which results in a data-dependent branch in the normalization code
	of at the end of gmp's mpz_import.
