fix warnings on darwin

- Subject: fix warnings on darwin
This fixes some warnings on Darwin.
Not really tested, because of
insn-attrtab.c: In function `internal_insn_latency':
insn-attrtab.c:18461: warning: ISO C forbids empty initializer braces
but at least the build gets to that point with -j2, which it didn't before.
