Currently, confirmed that -O0 in CFLAGS fixed the crash even with working
profile and cache, but slow. It would be llvm13/clang13 problem with
optimization, which bites firefox 117 but not 116 and earlier.

I'll report back if -O1 works or not. Now building with -O1.


Some details:
First, I've tested clearling (actually, moved) cache. It is still under
~/.cache/mozilla/firefox. It didn't help even with blank profile.

As I'm not sure how I can force -O0, to surely pick within poudriere build,
added "CFLAGS+= -O0" line in www/firefox/Makefile, which failed because "-O0
-O3" in the commandline invoked by make. Maybe the latter "-O3" was used.

Next, turned OPTIMIZED_CFLAGS off, with reverting the above-mentioned change.
This binary crashes, maybe because actually "-O2" was used.

So I've turned OPTIMIZED_CFLAGS on again, and patched Mk/bsd.gecko.mk with the
patch below. With this, "-O2 -O0" was used.
This worked with blank profile and cache. So made both blank again and copied
working ones there, still works! But slow.

Now -O3 and -O2 are known to crash. So buiding with -O1, modifying the patch
below.
Looking into running poudriere build log, "-O2 -O1" is used.
