[Qemu-devel] [PATCH] configure: Unify arm and aarch64 disas configury

[Peter Crosthwaite <crosthwaitepeter@gmail.com>]

From: Peter Crosthwaite <crosthwaitepeter@gmail.com>

The "arm" variant for this case already contains everything needed
for aarch64. As aarch64 already uses arm as a base architecture, it
will already have the CONFIG_ARM_DIS defined meaning no functional
change. So just make the configure code simpler.

Following this patch:

$ ./configure --target-list=aarch64-softmmu,aarch64-linux-user
$ grep DIS aarch64-softmmu/config-target.mak
CONFIG_I386_DIS=y
CONFIG_ARM_DIS=y
CONFIG_ARM_A64_DIS=y
$ grep DIS aarch64-linux-user/config-target.mak
CONFIG_I386_DIS=y
CONFIG_ARM_DIS=y
CONFIG_ARM_A64_DIS=y

Helps with multi-arch, less code paths to convert to multi-arch for
multi-arches many-way disas configury.
