Hi, I have been trying out the patch.  It definitely improves the situation on
rawhide.  However, I noticed when running the various examples testcases on
RHEL8 x86_64 there were additional failures:

 sudo make installcheck RUNTESTFLAGS="--debug systemtap.examples/check.exp"

Without the patch:


                === systemtap Summary ===

# of expected passes            408
# of unexpected failures        8
# of untested testcases         12

With the latest proposed patch:


                === systemtap Summary ===

# of expected passes            317
# of unexpected failures        99
# of untested testcases         12


Looking through the systemtap.log of the patched build see that not finding the
module_kallsyms_on_each_symbol:

PASS: systemtap.examples/general/also_ran build
meta taglines 'test_installcheck: stap also_ran.stp -T 1' tag
'test_installcheck' value 'stap also_ran.stp -T 1'
attempting command stap also_ran.stp -T 1
