The test of LINGUAS in po.m4 (code that is transferred to
configure/config.status) appears to allow for errors:


This check can have 3 outcomes, but I don't think that is the intent. From
what I can determine, the value of LINGUAS after this statement is supposed to
be either (1) what was LINGUAS before, or (2) the value "%UNSET%". But the
above code allows for a resulting value of null if the variable was set but

In the p11-kit (0.23.1) this problem appears, and current levels of the build
tools expose a failure when trying to build the language support files. The
p11-kit code erroneously sets LINGUAS='' in its configure.ac, which causes a
problem here. Right or wrong, this check can accommodate this mistake with a
small change.

The correct syntax should be:


(Note the colon before the hyphen) which will ensure that the result is either
the previous value or %UNSET%. Subsequent checks for %UNSET% will therefore
succeed, and the variable will never be null (empty) after this point.
