Subject: oe-buildenv-internal: Only add to $PATH if needed
X-Git-Tag: yocto-4.0~33284
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=161abcd3672f83990ede03d67b7388678c07150e;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

oe-buildenv-internal: Only add to $PATH if needed

If $PATH already has the needed paths at the beginning, there is no need
to add them again. This allows rerunning oe-init-build-env for the same
directory without having $PATH increase unnecessarily every time.
