[Qemu-devel] [PATCH 13/39] properly detect compiler in tests/Makefile

[Paolo Bonzini <pbonzini@redhat.com>]

`make speed' only makes sense if not cross-compiling, so sha1 can
use the CC for the system that is hosting qemu.  sha1-i386 is also
wrong, since there is usually no variable for the target CC; guess
some plausible values.
