Subject: scripts/package-metadata.pl: fix handling transitive conditional dependencies
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fstaging%2Fhauke.git;a=commitdiff_plain;h=6c3eff9dd8bb8d0f268e8a0dbedbc6a33bdac796

scripts/package-metadata.pl: fix handling transitive conditional dependencies

When a package foo depends on PACKAGE_foo:bar (in order to make build
dependencies conditional), tracking transitive dependencies can fail because
the internal seen flag is checked/set before eliminating the fake conditional
dependency. This can show up as a depends on not properly turned into a
select further down in the dependency chain
