Subject: ref-manual: Updated the PACKAGES variable description
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=826383984d5b4d8ca5c3a7bbcf4bcc0d4a5b55d8;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

ref-manual: Updated the PACKAGES variable description

Fixes [YOCTO #10294]

Provided text noting that if packages in the PACKAGES list are
empty are not generated, unless generation is forced through
the ALLOW_EMPTY variable.

(From yocto-docs rev: 1c89e0edf7e038f733b9b95bb884648d953b9574)
