I tested a variant of this patch with --target=arm-linux-gnueabihf.
During the ‘configure’ phase, I see:

--8<---------------cut here---------------start------------->8---
Checking for cross-compile
No targethost for running compiler tests against defined, running locally
--8<---------------cut here---------------end--------------->8---

Then the build completes but the result is a set of x86_64 (native)

So I suppose some more work in needed to really cross-compile.  Maybe we
need to pass specific configure flags?

(BTW, I think I already wrote this but you don’t need to cross-compile
if all you want is 32-bit binaries.  Simply use “-s i686-linux” for
