[Qemu-devel] Missing dependency checks in qemu build

[Matthew Fernandez]

Hi all,

This only came to my attention when building qemu on a colleague's machine recently, but there are 
some dependencies for the build that are not detected during the standard `configure` process. In 
particular, missing autoconf was not detected until running `make` itself. Also missing libtool 
produced a fairly obtuse error. It was reasonably apparent to me what went wrong, but thoroughly 
confusing to my colleague.

Should the configure process be made more bulletproof? Perhaps assuming the existence of these 
things seems fine to others. I don't know what the status quo is here. By the way, this is with 
reference to the qemu 1.7.0 release. I'm not on the list currently, so please CC me when replying.

Thanks,
Matt
