'make -k install-headers' stops sufficiently far into the process for me,
as I recall.  I haven't tried this in some time, but I'll be going back to
it soon.

I actually configured GCC using a non-cross-compiler and a cross --target=,
and got "good enough" results to get headers installed; then I built GCC
properly, and then glibc properly.  There are some bootstrap issues here
however.

Completely agree.... both of our techniques are a little hackish.  This worked
before GCC started requiring libc headers to build libgcc.
