Comment:
@ericonr, thanks for the suggestion! Indeed I could get around defining a custom `do_install()` by setting `$make_install_args="STRIP=-s"`...

However, Makefile uses `$(STRIP)` as options to `install`:
https://github.com/alexpevzner/sane-airscan/blob/master/Makefile#L118-L132

and defaults to `-s` (which instructs `install` to strip):
https://github.com/alexpevzner/sane-airscan/blob/master/Makefile#L30-L35

so, for cross-compilation, I think we would need to override `$(INSTALL)` with `target-linux-gnu-install` ~ which could be a nice addition to the gnu-makefile build style, as it already does many similar overrides for `CC`, `LD` and friends.

What do you think?
