Last time we went through this, didn't we discover that one has to set

 FLAGS_FOR_TARGET (instead of CFLAGS_FOR_TARGET or CXXFLAGS_FOR_TARGET)

and

 on the "make" command line (instead of through the environment or as
 a ./configure argument)

?  Yes, I know it is clunky.

Reassigning to "general" because the underlying problem (Debian as a
whole is moving to multiarch paths, and we don't provide enough help
with building upstream toolchains that don't know about that) is not
at all specific to libc6-dev.  Progress in the form of code or
documentation, in Debian or upstream, would be welcome as always.

Cheers,
Jonathan
