[Aboriginal] Failures with qemu-1.6

[Patrick Lauer]

Testing 1.2.5 on amd64 (Gentoo) with qemu 1.6.0 the mips64, sh4, armv6l
and sparc targets fail to pass the smoketest.

In a way I'm not really surprised how fragile things are, but ... sigh :)

armv6l seems to have a problem with the virtual sound hardware in qemu:

system-image-armv6l $ ./run-emulator.sh
Uncompressing Linux... done, booting the kernel.

/chroot/build/portage/media-libs/alsa-lib-1.0.27.2/work/alsa-lib-1.0.27.2/src/pcm/pcm.c:7843:(snd_pcm_recover)
underrun occurred

sparc seems to have a problem in the compiler:

(sparc:1) /home # df

exit

/tmp/hello: symbol '__gcc_personality_v0': can't handle reloc type 0x17
(sparc:1) /home # exit

mips64 seems to have invalid executables:

9pnet: Installing 9P2000 support
