That'd be a bit of a pain, since (afaict) patchelf is not so widely
available in host distributions as chrpath.

I agree that removing the weird and arbitrary-seeming (from the user
perspective) restriction on rpath length would be a good thing.  But
it's less clear that swapping a weird restriction that few people will
ever run into for a requirement to pre-install a relatively obscure host
binary on all systems is a good tradeoff.

How about writing a python function, or a trivial standalone program
(which can be compiled -native without requiring anything other than
${BUILD_CC}) to preprocess the binaries before chrpath sees them, or
indeed just to replace chrpath altogether?  Or, as an alternative, how
about fixing chrpath to suck less and then just waiting for the improved
version to trickle down into deployed host distributions?
