[PATCH v2] perf build: Revert "enable -fno-strict-aliasing"

[Ian Rogers <irogers@google.com>]

This reverts commit 55a18d2f3ff7 ("perf build: enable
-fno-strict-aliasing"). With (get|put)_unaligned_* using memcpy
-fno-strict-aliasing is no longer necessary as memcpys are assumed to
possibly alias.
