Compiling mainline for i686-linux-gnu I got these warnings:
insn-attrtab.c:42278: warning: unused variable `temp'
insn-attrtab.c:42276: warning: unused parameter `chip'
insn-attrtab.c:42300: warning: unused variable `temp'
insn-attrtab.c:42298: warning: unused parameter `chip'
The appended patch fixes the warnings, bootstrapped/regtested on
i686-linux-gnu.
Ok to commit?

* genautomata.c (output_internal_min_issue_delay_func): Add
ATTRIBUTE_UNUSED to avoid warning with empty dfa.
(output_internal_trans_func): Likewise.
