Julien Floret 4bdb067e38 infra: remove auto derivation of host dependencies
This feature consists in automatically deducing dependencies of a host
package from the dependencies of the target variant.

However, it causes some issues, and many host packages need different
dependencies than their target variants.

Now that host dependencies are explicitly set for all packages, we can
remove it.

# CMake package infrastructure
#
# This file implements an infrastructure that eases development of
# package .mk files for CMake packages. It should be used for all
# packages that use CMake as their build system.
#
# See the Buildroot documentation for details on the usage of this
# infrastructure
#
# In terms of implementation, this CMake infrastructure requires
# the .mk file to only specify metadata information about the
# package: name, version, download URL, etc.
#
# We still allow the package .mk file to override what the different
# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
# already defined, it is used as the list of commands to perform to
# build the package, instead of the default CMake behaviour. The
# package can also define some post operation hooks.
