Subject: Allow setting empty environment variables
X-Git-Tag: v15~213
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a74cea3e96a394336f3777e1f6e01ef8af615f19;p=thirdparty%2Fmkosi.git

Allow setting empty environment variables

Trying to set an empty environment variable with `FOO=` would instead
pass the `FOO` variable from the host, which is the expected behavior
when `=` is missing.
