--disable-gcc-check in qemu's configure just shortcuts all the tests to
validate that the compiler to be used is gcc-3.x and that defaults to "gcc"

in the case of kvm's configure, using "gcc" as the default compiler will be
the case if :

1) the user didn't provide his own --qemu-cc preference
2) gcc-3.x couldn't be found when searching by name in /usr/bin/

and which is the expected behavior on qemu when --disable-gcc-check is used.

Carlo

PS. ideally host_cc should be by default "${CC}" if defined but using "gcc" is
what qemu's configure does so did the same for consistency reasons
