I need to hassle Sam about that.

Sam, why do we have FORCE on the rules for $(hostprogs-y)? It forces the
ihex2fw tool to be rebuilt, which in turn forces all .HEX->.fw
conversions to happen again, which means that 'make modules_install'
wants to write to the source tree. That's a problem in some strange
situations like Rafael's, where he builds on another host and exports
the tree read-only by NFS.

Can we do this? ...
