I've managed to get postinstall to install the i386 MAKEDEV
into my sparc filesystem.

I'd done a build.sh -m sparc ... install and the postinstall check
reported a load of errors (not surprising since the target filesystem
was empty when I started).  Anyway at the end it outputs:

To fix, run:
    /bsd/src/etc/postinstall -s /bsd/src -d /sparc_root ...

So I duly cut and paste the command to execute it.

Unfortunately postinstall relies on MACHINE being set in the environment.
So it pulled in the i386 MAKEDEV.

The following patch adds a '-m machine' option to postinstall.
