Your cross-libfoo-dev package would have to solve this. Usualy the
cross-libfoo-dev package would only contain the *.so link in
/usr/lib/arch-os-libc/ and depend on the normal -dev package. Only
when the library has architecture specific include files (not in the
architecture specific dir) would you need to move header files
around. Short term in dpkg-cross, long term in the debian package
itself.

For multiarch the problematic part is actually just splitting out the
*.so links into an arch:any package and common header files into an
arch:all package. A lot of work to modify rules files and lots of new
tiny debs for the archive (and NEW processing). So it got put off for
later. Your dpkg-cross can automatically do this in 99% of cases
leaving verry little handholding.
