[Qemu-devel] [PATCH v2] configure: Don't implicitly hardcode list of KVM architectures

[Peter Maydell <peter.maydell@linaro.org>]

The code creating the symlink from linux-headers/asm to the
architecture specific linux-headers/asm-$arch directory was
implicitly hardcoding a list of KVM supporting architectures.
Add a default case for the common "Linux architecture name and
QEMU CPU name match" case, so future architectures will only
need to add code if they've managed to get mismatched names.
