[kvm-unit-tests PATCH v1 1/5] configure: Document that the architecture name 'aarch64' is also supported

[Alexandru Elisei]

$arch, on arm64, defaults to 'aarch64', and later in the script is replaced
by 'arm64'. Intentional or not, document that the name 'aarch64' is also
supported when configuring for the arm64 architecture. This has been the
case since the initial commit that added support for the arm64
architecture, commit 39ac3f8494be ("arm64: initial drop").

The help text for --arch changes from*:

   --arch=ARCH            architecture to compile for (aarch64). ARCH can be one of:
                           arm, arm64, i386, ppc64, riscv32, riscv64, s390x, x86_64

to:

    --arch=ARCH            architecture to compile for (aarch64). ARCH can be one of:
                           arm, arm64/aarch64, i386, ppc64, riscv32, riscv64, s390x, x86_64

*Worth pointing out that the default architecture is 'aarch64', even though
the rest of the help text doesn't have it as one of the supported
architectures.
