hi, nick, dave!

first of all, thanks for the review; appreciate the comments (and
eagerly awaiting yours, dave).

sure: I expect erich to have the final say in the copyright assignment
issues, so he'll comment on this.

not me. once again, it's erich's call.

well, the linux toolchain is a bit experimental and not really ready for
public consumption yet (there is also no publicly available kernel yet),
so perhaps it would be best to leave it out of the upstream patch - I
can maintain it in a private tree easily.

(it really is used to build a variant of a radically trimmed down linux
kernel, https://software.sandia.gov/trac/kitten , which we are currently
porting to SX and is intended for use in computational clusters, not
unlike CNL. and yes, our port really is a COFF based kernel as we dont
have an ELF bootloader yet. anyway, it is expected that it will be
obsoleted by a future ELF toolchain for Linux on SX.)

sure. I'll check the testsuite status for the *-superux toolchain and
fix any outstanding issues.

that said, I'll be happy to provide another patch that omits the linux
toolchain and fixes any possible SX testsuite issues - as it will be
almost identical to this one, I suppose another in-depth review will not
be necessary. let's just wait for dave's comments about COFF internals
first ...

it's a shrink-wrapped offer: a maintainer comes with the patch. ;) not
sure about the name yet, but there will be one, of course.
