Subject: Globally disable PKG_CONFIG_PATH
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=670cb306704d76b4c3b717931cc7abef8c693099;p=buildroot.git

Globally disable PKG_CONFIG_PATH

If PKG_CONFIG_PATH is set in the environment, it allows pkg-config to
look for libraries outside of the buildroot tree.  This is a problem
both for host and target builds.  To avoid it, globally set an empty
PKG_CONFIG_PATH in the environment.
