lang/spl: Fix build on modern gcc

I don't know why spl builds on clang but fails on gcc due to a flex
precedence issue.  Rather, I don't know why the flex issue doesn't affect
clang.  There was a patch provided by a fork nearly four years ago that
fixes the gcc build nicely.  The bitbucket issue warns that more eyes
should review the fix though.
