Hum, you're right. But I think I would still like to keep a "enable
debug" option that would :

 * Compile with -g and keep the unstripped binary in the staging/
   directory

 * Strip the binaries in target/

This is the normal setup needed to do remote debugging: stripped
binaries on the target, unstripped binaries with debugging symbols to
feed gdb on the host.

I don't have a very strong opinion on this, but I think having an
option for debugging/non-debugging is useful (and debugging + stripping
should probably be the default). But if we decide to get rid of the
option, some documentation would probably be enough.

Sincerly,

Thomas
