Not setting it at all results in the manual pages getting incorrectly
installed in /share/man/manX/ as shown in the previous e-mail. This is
a bug. It should inherit prefix, but it somehow doesn't.
Explicitly setting --mandir=/usr/share/man obviously works, but should
not be needed if prefix was correctly inherited.
