Subject: utils/test-pkg: clean output dir for successful builds
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=72bf48606cc5ccf5c48c631d265cbe52d8001a62;p=buildroot.git

utils/test-pkg: clean output dir for successful builds

test-pkg will use gigabytes of space when testing all toolchains.
Nevertheless, you are normally only interested in the actual build / host
tree when there is a build failure.

Do a 'make clean' for successful builds to save disk space, unless the new
option '-k/--keep' is set.
Note that the logfile and configuration is always retained for inspection.
