[PATCH] mig: Drop the Perl runtime dependency

[David Michael]

* mig.in (libexecdir_rel): Compute with realpath instead of perl.
---

Hi,

I tried running mig on a system without Perl ealier with bad results.
Perl seems to be used only for functionality that is also provided by
GNU coreutils (which is already required, e.g. for dirname).  Does it
make sense to drop the Perl command in favor of using realpath here?

Thanks.

David
