This test expects a single mention of stack_chk_fail, as part of a
call sequence, but when e.g. PIE is enabled by default, we output
.hidden stack_chk_fail_local, which makes for a count mismatch.
Disable PIC/PIE so as to not depend on the configurable default.
Regstrapped on x86_64-linux-gnu, also tested with gcc-13 on i686- and
x86_64-. Ok to install?
for gcc/testsuite/ChangeLog
* g++.dg/pr58245-1.C: Disable PIC/PIE.

More tolerance and less prejudice are key for inclusion and diversity
Excluding neuro-others for not behaving ""normal"" is *not* inclusive
