Well, I was going to change all the -O3 in python's configure files
to -O2, but just above the first was a test which if met would set it
to -O0 : turns out tere is a --with-pydebug configure switch.
After rebuilding python with that, and unsetting CFLAGS before the
configure, I now got:
root@plexi /home/ken #python2-config --cflags
-I/usr/include/python2.7 -I/usr/include/python2.7
-fno-strict-aliasing -g -O2 -g -O0 -Wall -Wstrict-prototypes
[29729 refs]
which seemed a bit odd (the last line, and the initial -g -O2), but
rather more hopeful.
Unfortunately, that breaks attempting to build firefox-47 :

Note the win7 directory. I assume that the pythonic stuff is not
going to work with -O0, so I'll have to restore how python was.
Meanwhile, the existing firefox is still running (seems reasonably ok
on non-videos, and often ok on those too), but I can no longer attach
gdb to it - it advises relinking which is fair enough (i.e. python).
