Subject: package/pkg-utils.mk: rework implementation of extractor-system-dependency
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2e42840e2ae1a4279b00e0db6b197ca6f3a0df3a;p=buildroot.git

package/pkg-utils.mk: rework implementation of extractor-system-dependency

Now that we have the EXTRACTOR_PKG_DEPENDENCY.* variables available,
we can use them to implement extractor-system-dependency: if for a
given archive type, the corresponding EXTRACTOR_PKG_DEPENDENCY.<type>
variable is empty, then it means we need the corresponding extractor
tool to be provided by the system.

Following this, EXTRACTOR_DEPENDENCY_PRECHECKED_EXTENSIONS is no
longer used, so we can drop it from support/dependencies/.
