[9fans] Rune update may have broken compilations

[lucio]

...  or I may just be doing something inappropriate.  But right now, I
get:

        5c -FTVw runebase.c

when compiling libc, whether for the 386 or the arm.

I'd appreciate suggestions on how to get out of this trouble.  I've
already made sure both 8c and 5c match the versions in sources.
