Yes. lib-y will be used for libcompel.so (and compel.a) which is not
a host program but rather a part of distribution. The compel-cli
won't be shipped at the moment, because hostprog mode is exatly
to use some "host-cc" and other flags to build program that runnable
on the platform where we build criu itself.

That said if we decide that we need to build compel-cli as a
part of criu and ship it together with criu as own executable
program -- than I have to rework all this and build piegen
separately. But even if so let do it on top.
