perf tools: Remove -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.
