Perl fails to build on arm/armeb with -O2 optimization and current gcc4.
with -01, perl compiled fine and pass testsuites withoout a problem. By
using the following patch instead of the current 63_debian_ppc_opt..
patch, this (gcc) issue can be worked around.

Building a new package now. I've dropped the optimisation on only the
following files (which proved to be the source of the problem on other
architectures): pp_ctl.c, pp_hot.c and pp_sort.c .

If this doesn't fix the problem, re-open and I'll drop everything to
-O1.

Would have tested this first, but unfortunately there doesn't seem to be
an arm machine available for developers right now...

Drats. That didn't work.

While I can simplly drop the optimisation level entirely, I've been able
in the past to do so only on specific problem code (which is my
preference).

A login to an unstable arm box would help a lot (hence the CC to Vince).

Please also enable the workaround for the armeb (big-endian ARM)
arch. The original patch from Riku checked for arm*, which does
include armeb, but the patch that went in checks for arm-*.
