>Description:
    After two consecutive builds, using build.sh with identical settings,
    including MKREPRO=yes, the usr/share/info/dir files under the two
    DESTDIRs may be different.  For example, I see the following differences:

--- DESTDIR.1/usr/share/info/dir
+++ DESTDIR.2/usr/share/info/dir

>How-To-Repeat:
    Checkout a NetBSD-current tree;
    build.sh -V MKREPRO=yes -D DESTDIR.1 -j 4 [more options];
    build.sh -V MKREPRO=yes -D DESTDIR.2 -j 4 [more options];
    diff -U3 DESTDIR.1/usr/share/info/dir DESTDIR.2/usr/share/info/dir

>Fix:
    I suspect that this may be related to the order in which
    the parallel make decides to apply several updates to the
    info dir.
