Subject: toolchain-scripts: Allow the CONFIGSITE_CACHE variable to be overridden
X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=d343c6a7369cb409563b8149cbb423a6171221ee;p=openembedded-core.git

toolchain-scripts: Allow the CONFIGSITE_CACHE variable to be overridden

In multilib and baremetal configurations, this variable can cause a variety of
problems due to the use of TCLIBC. At least allowing it to be overriden
is a start and allows various configurations to avoid the issue.
