BUILD: pattern: work around an internal compiler bug in gcc-3.4

gcc-3.4 fails to compile pattern.c :

src/pattern.c: In function `pat_match_ip':
src/pattern.c:1092: error: unrecognizable insn:
(insn 186 185 187 9 src/pattern.c:970 (set (reg/f:SI 179)
        (high:SI (const:SI (plus:SI (symbol_ref:SI ("static_pattern") [flags 0x22] <var_decl fe5bae80 static_pattern>)
                    (const_int 8 [0x8]))))) -1 (nil)
    (nil))
src/pattern.c:1092: internal compiler error: in extract_insn, at recog.c:2083

This happens when performing the memcpy() on the union, and in this
case the workaround is trivial (and even cleaner) using a cast instead.
