Subject: [PATCH] perf tools: Kill off -Wcast-align

The present use of -Wcast-align causes the build to blow up on SH due to
generating a "cast increases required alignment of target type" error on
each invocation of list_for_each_entry().

It seems that this was previously reported and killed off in the ia64
support patch, but nothing seems to have happened with that. Presumably
the same problem still remains there, too.
