v86d: Make cross compilation working on more architectures

Browse Source 
Since commit 709c603dec19 ("v86d: Accept aarch64 as build host") we
support cross compilation on aarch64 host in addition to x86 host.
However building on hosts different than two above will fail.

Make cross compilation support more generic by checking for TARGET_ARCH
in v86d configure script with fallback to `uname -m` when not present in
environment and pass TARGET_ARCH explicitly in do_configure().

Cross build for x86 tested on IBM Power 8 machine with RHEL7. Should
work on aarch64 and rest too.

Subject: v86d: Support for cross compilation
It is common to build on one system for another (e.g. on IBM Power
machine for Intel x86) where HOST_ARCH (uname -m) != TARGET_ARCH.
Take TARGET_ARCH from environment if it is given, otherwise fall back
to `uname -m`.
