[Libguestfs] hivex: Bug: RPATH in Perl SO

[TJ]

Whilst cleaning up the lintian reports in preparation for the
Debian/Ubuntu hivex package one of the issues is:

E: libhivex-perl: binary-or-shlib-defines-rpath
./usr/lib/perl/5.10.1/auto/Win/Hivex/Hivex.so
/tmp/buildd/hivex-1.2.1/perl/../lib/.libs

I've temporarily dealt with this by using chrpath in the build and a
rule to delete the RPATH from "auto/Win/Hivex/Hivex.so".

I wonder if this is an oversight since it is non-portable and refers to
a build-time location? There are some helpful notes about this at:
