It should be more like <nothing>.  aicasm runs on the host, so it should
be compiled with the host headers wherever they are.  If they are not
in /usr/include, then the above is broken.  But -I/usr/include is needed
to recover from -nostdinc.  -nostdinc is either a vestige of historical
foot-shooting or needed for "-I. -I/share/src/HEAD/sys/dev/aic7xxx/aicasm"
to work right.  I'm not sure which.
