Yep.

As of now, we have INHIBIT_PACKAGE_STRIP that switches stripping, but it has 
strong on/off semantics, so I don't think we can change that. We can replace 
it with some common PACKAGE_STRIP setting that would work like this:

# No stripping
PACKAGE_STRIP=no
# Strip but leave .gnu_debuglink for debugging
PACKAGE_STRIP=debug
# Strip everything
PACKAGE_STRIP=full

But that's more intrusive and will force distro and local config updates. I 
can do it if everyone is OK with such change.

And, BTW, we also have DEBUG_BUILD setting, although that just switches 
compile flags from what I see.
