The existing sed to manipulate the exec line is arguably a better
solution to making this package machine-specific and special-casing
just qemuarm.  (I'm not sure why it special-cases qemuarm, and
751212d5effdceab91d95705e647cf07e6820940 where it was introduced
doesn't clarify matters, but we'll ignore that for now).  Arguably,
but I'm not sure I agree.  Anyway, you've a path that is known at
build time so we can fix it at build time.  Instead of using install,
you can use sed.  Just because we *can* run postinst scripts when
generating the rootfs doesn't mean we *should*, do_install is for
installing the files we're going to package, and postinst is for
runtime changes that can't happen at any other time.

We're not being invoiced based on the number of patch hunks, and
changing /sbin to @SBIN@ and install to sed isn't exactly a massive
time sink.
