aic7xxx/aicasm manpage

My kernel build is busted, it can't find:

cd ../../../modules; 
MAKEOBJDIRPREFIX=/usr/src/sys/amd64/compile/JULY/modules 
KMODDIR=/boot/kernel DEBUG_FLAGS="-g" MACHINE=amd64 
KERNBUILDDIR="/usr/src/sys/amd64/compile/JULY" make  all
===> aac (all)
===> accf_data (all)
===> accf_http (all)
===> agp (all)
===> aha (all)
===> aic7xxx (all)
===> aic7xxx/aicasm (all)
make: don't know how to make aicasm.1. Stop
*** Error code 2

Stop in /usr/src/sys/modules/aic7xxx.
*** Error code 1

Stop in /usr/src/sys/modules.
*** Error code 1

I know that to fix this, the simplest way is to merely stick a
NOMAN= <empty>

into the Makefile at /sys/modules/aic7xxx/aicasm.  I don't know if 
that's the way you'd want to fix it, but it seems to break the build for 
me, so a prompt fix is in order, I think.
