Interesting question. I do use busybox as my userland for most purposes,
but in case of sed I believe it really is the gnu sed.
which sed
/usr/bin/sed
/usr/bin/sed --version
GNU sed version 4.1.5-boot

sampo@jin:/aino/linux 0$ /bin/sed --version
This is not GNU sed version 4.0
The former, which is gnu sed, should be picked up by PATH. The latter
which appears to be picked by make, is the busybox sed. The gnu sed was
compiled by me for my own distro, hence -boot label, but has not been
stripped down in any way.

The latter. Which one is correct? Is asm-offsets.h the output of
the above command? Please confirm.
Since on command line it seems to work fine,
but in make time it bombs, I suspect make somehow manages to find
the busybox sed, which verifiably produces output

Thus this is probably a PATH issue of some sort. I will investigate,
but will not delay this response.
Of course as a mild feature request, please fix the sed parts to
be more tolerant of lesser seds.
