We can have a single target and include both host as target in the 'toolsets'
option.

Unfortunately I didn't manage to make it work that way. I have this kind of
warning when running make:
tools/android/md5sum/md5sum.target.mk:231: warning: overriding commands for
target `out/Debug/md5sum'
tools/android/md5sum/md5sum.host.mk:183: warning: ignoring old commands for
target `out/Debug/md5sum'.

I tried many different approaches, one of them being having a single 'md5sum'
simple target with toolsets = ['host', 'target']. Nothing worked :/
