The introduction of <pkg>_STRIP_COMPONENTS broke the build of the
target tar package, because support/dependencies/check-host-tar.mk
defines TAR_STRIP_COMPONENTS to --strip-components. Which leads to
have the package infrastructure do:
$$(TAR_STRIP_COMPONENTS)=$$($(2)_STRIP_COMPONENTS)
which for the tar package evaluates to:
$$(TAR_STRIP_COMPONENTS)=$$(TAR_STRIP_COMPONENTS)
which evalutes to:
--strip-components=--strip-components
Which obviously doesn't work really well. And in fact the
TAR_STRIP_COMPONENTS definition in
support/dependencies/check-host-tar.mk is no longer necessary: it was
needed in the days where we were trying to support old tar versions
that did not support --strip-components. But nowadays, when such an
old tar version is encountered, we build our own host-tar which
supports --strip-components.
