[committed] Fix microblaze build with rtl checking enabled

[Richard Sandiford]

This typo didn't matter for normal builds because INTVAL provides the
missing brackets.  It didn't build with rtl checking enabled because
the __extension__ got in the way.

Tested on microblaze-elf and committed as obvious.

Thanks,
Richard
