Subject: include: add umask prereq check
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5f80315634c66a647aed9673e10582acd8462d69;p=openwrt%2Fstaging%2Fluka.git

include: add umask prereq check

When building LEDE with umask values other than 022, the resulting packages
will embed improper permissions, which may lead to random errors or non-
functional scripts on the target.

In order to make users aware of this problem, add a build-prereq check to
assert a correct umask setting before starting the build.
