dietlibc has traditionally not contained any FPU emulation, because on
most platforms that was always done in by the compiler in libgcc. If
that has changed, i.e. this stuff is moved to glibc, then obviously
this should be ported over to dietlibc. I'd be willing to do that, but
I don't have access to PowerPCSPE hardware. Of course, I could play
the game of "let's try something and upload to experimental and see
what the buildds do", but my previous upload of dietlibc to
experimental (unrelated to this bug) isn't even built yet on ppcspe,
so I'd rather not do that. Is there any way to get access to some
hardware to test this? I asked around in IRC a bit and was told that
ppcspe isn't bootstrapped yet, so my guess is that there's no official
porterbox access, right? Is there any hardware you have where I could
get access to? [1]

[1] Of course, if you know how to properly set up a qemu-based chroot
on amd64, that'd also be sufficient for me. But I did try to
debootstrap with the http://antcom.de/powerpcspe/ repository
according to <https://wiki.debian.org/PowerPCSPEPort>, but
qemu-ppc-static doesn't like it and I get "illegal instruction",
regardless of what binary I try to execute. qemu-ppc-static does
work for the 'powerpc' architecture in that fashion. (I'm using
QEMU 2.5 btw.)
