package/pkg-generic: handle host-lzip as an extract dependency
This moves the host-lzip dependency handling from
DEPENDENCY_HOST_PREREQ to an extract dependency.
To achieve that, check-host-lzip.mk fills in the
BR2_LZIP_HOST_DEPENDENCY with host-lzip if building a host-lzip is
needed. The name BR2_LZIP_HOST_DEPENDENCY has been chosen because it
matches the name BR2_CMAKE_HOST_DEPENDENCY already used in
check-host-cmake.mk.
The BR2_LZIP_HOST_DEPENDENCY is added to all packages, except:
- host-lzip, because we would otherwise depend on ourself.
- host-tar, because lzip itself is delivered as a tarball, so we need
to have host-lzip depend on host-tar, and not host-tar depend on
host-lzip
- host-skeleton, because we need to have host-lzip depend on
host-skeleton, and not the opposite.
We also mutually exclude host-lzip and host-xz from dependending on
each other, to avoid a circular dependency.
In addition, we modify lzip.mk to explicitly build host-lzip without
ccache. We generally took the approach of building host-ccache *after*
all the extractors have been built.
