textproc/pinfo: fix for -fno-common and -O0

Obvious fix to avoid duplicate definition of use_manual. The conversion
from inline to static inline fixes the build with -O0. I ran into that
because I tested with CFLAGS=-fno-common which removed -O2. I can land
that separately if desired. Regen plist while there.
