Log Message:
The "binary relocate" support (in src/prefix.*) parses /proc/self/maps and
expects pathnames.  Older NetBSD kernels don't provide the path, leading to a
failure to locate the right path prefixes.  Being Pkgsrc, we're not really
interested in leaving these decisions to run-time anyway, so just disable this
behaviour outright.

Bump PKGREVISION.
