Subject: scripts/package-metadata.pl: honour DEFAULT_VARIANT
X-Git-Tag: v17.01.0-rc1~974
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=12d15fa8a5096913927d75958d0ed3af9d963e73;p=openwrt%2Fstaging%2Fchunkeey.git

scripts/package-metadata.pl: honour DEFAULT_VARIANT

So far, package-metadata.pl always considered the first provider of a virtual
package to be the default variant which might deviate from what buildroot
considers to be the default.

Change the Kconfig dependency / select code generation for virtual package
providers to consider the DEFAULT_VARIANT to be the primary provider and only
fall back to the first provider if no default variant was explicitely tagged.
