First, why one would want to require that gitweb version (version at
the time of build) and runtime git version (version of git used to run
commands) match?
Second, it is mismatch, not missmatch (one 's', not double 's').
Third, in my opinion it would be better to name variable in question
e.g. $versions_must_match and also flip its meaning (true means check
that versions match, and show an error otherwise).

First, 'undef' is false, so it could have been written as
+our $missmatch_git;
Or if you prefer explicit false-ish value as default, 0 would be I
think better than empty string '':
+our $missmatch_git = 0;
Second, there is question whether default should be to allow
mismatched versions (current behaviour, more lenient...) or deny (or
warn about) mismatched version, i.e. should it be $versions_must_match
false by default, or $allow_versions_mismatch false by default.

Could you please clean up language in above comment? It is very
convoluted. Please also limit line width of above comment to 76 / 80
columns.

Style

Do not compare $missmatch_git / $allow_versions_mismatch against '':
it is a boolean value!

Shouldn't this be "500 Internal Server Error" or something (using the
optional parameter to git_header_html())?

Too long lines. Here-doc could be better here.
