Subject: [build] Avoid using sha1sum when calculating build ID
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3a2411b43f840f11f667a22d061d01826f75f818;p=thirdparty%2Fipxe.git

[build] Avoid using sha1sum when calculating build ID

The sha1sum command may not be available on all systems.  Use the
POSIX-confirming cksum instead.
