lang/perl5 from -current fails to build on AIX 7.1

[Louis Guillaume <louis%zabrico.com@localhost>]

Hi,

Once again I'm stuck with my AIX pkgsrc environment. This time it's with 
lang/perl5. I really appreciate anyone reading on...

I'm using gcc - xlC is too expensive! Also I noticed that the "Toolbox 
for Linux Applications" is now using gcc for many things including 
perl5, so I'm back to using gcc-8.3.0 (from the toolbox). For pkgsrc, 
the -current branch is in play.

Bootstrap works (I did have to patch a couple things but don't want to 
get into those weeds here) and I needed "-02" in CFLAGS to get past some 
weird configure issues I posted about here before 
(https://mail-index.netbsd.org/tech-pkg/2020/06/05/msg023298.html).

Below is a log of the error, "Illegal instruction". I've included an 
"ldd" of the perl binary that fails to run. The RPM specfile for a 
supposedly working version - I have not verified that it builds on my 
system - can be found here: 
http://public.dhe.ibm.com/aix/freeSoftware/aixtoolbox/SPECS/perl-5.30.2-1.spec

Any help, hints, suggestions would be great.
