No need. I got the test to pass. I forgot to run paxctl +m on the
pcre2_jit_test binary.

	$ paxctl +m .libs/*
	$ make check
	make  check-am
	make  
	make  all-am
	make  check-TESTS
	PASS: pcre2posix_test
	PASS: pcre2_jit_test
	PASS: RunTest
	PASS: RunGrepTest

I did that and the sljit tests seem to have all passed

	$ ./bin/sljit_test -v
	Run executable allocator test
	Run test1
	Run test2
	...
	no simd available, simd tests are skipped
	SLJIT tests: 1 (0%) tests FAILED on ARMv6 32bit (little endian
+ aligned) ABI:softfp (with fpu)

There were no error messages and the count of one failure is because
test64 was commented out, leaving the number of successful tests one
short from the expected total.

For completeness, here is some information about the test system I ran
these tests on.
