qapi: add 'query-target' command to return target arch

Add a 'query-target' QAPI command to allow management applications
to determine what target architecture a QEMU binary is emulating
without having to parse the binary name or -help output

configure: Don't override user's --cpu on MacOS and Solaris

Both MacOS and Solaris have special case handling for the CPU
type, because the check_define probes will return i386 even if

these checks earlier in the configure probing so that we can...

Support using a different compiler for Objective-C files

MacOSX 10.8 ("Mountain Lion") requires us to compile our one

configure: Fix set-but-not-used warning in Xen 4.1 probe

The Xen 4.1 probe never uses the return value from xc_interface_open(),

configure: -march=i486 belongs in QEMU_CFLAGS, not CFLAGS

The distinction between QEMU_CFLAGS and CFLAGS is that the

the latter is for flags like "-g -O2" which the user can
safely override. "-march=i486" is in the former category, and...

Since commit 417c9d72d48275d19c60861896efd4962d21aca2 all configure tests
