[PULL 23/30] configure: Loosen GCC requirement from 7.5.0 to 7.4.0

[Paolo Bonzini <pbonzini@redhat.com>]

From: nia <nia@NetBSD.org>

As discussed in issue 614, we're shipping GCC 7.4.0 as the
system compiler in NetBSD 9, the most recent stable branch,
and are still actively interested in QEMU on this platform.

The differences between GCC 7.5.0 and 7.4.0 are trivial.
