qemu: remove 0.9.x
QEMU 0.9.x is obsolete this days and with all modifications made for QEMU 0.10.x in OE, versions 0.9.x are unusable anyway. 0.10.3 was introduced 10 month ago, so a good transition time was also given. Now it's time to just kill it. Also remove cvs and svn versions since those are 0.9.x leftovers and QEMU moved to git long ago. Also remove gcc3 checks since that are not relevant for QEMU 0.10+. Also remove from icecc blacklist, since QEMU builds fine with it and the reason for blacklisting was GCC 3.
