problem cross-compiling 9.1

[Daniel Braniss]

reposting to hackers, maybe better luck here?

When using an amd64 host to 'make TARGET_ARCH=i386 buildworld' it seems that
it's using the wrong cpp, at least when building ioctl.c via mkioctl in
usr.bin/ktrace and having set WITHOUT_CPP(*). This used to work with
previous releases.

...
===> usr.bin/kdump (depend)
env CPP="cpp"  sh /r+d/stable/9/usr.bin/kdump/mkioctls 
/home/obj/rnd/alix/i386.i386/r+d/stable/9/tmp/usr/include > ioctl.c

*: Im compiling for an embedded system, and hence I want the minimum stuff.

at the moment the work around is to remove the WITHOUT_CPP, but it got me
worried.

any fix?

cheers,
