The normal pkgsrc build of the rust bootstrap kit embeds
/usr/pkg/lib as part of the runpath, so that the curl library is
found.

The problem is that as a package builder, I can't know what other
people set their PREFIX to, and the package depends on a binary
bootstrap (the previous-version rust bootstrap kit).  So I can't
know a priori what to put in the runpath in the binary bootstrap.

One option is of course to tell people who set PREFIX to
something else than /usr/pkg that they need to patch the binary
bootstrap kit's executable with patchelf as per the above.  Not
the best solution, but a workaround.
