The proc-empty-vm test is implemented for x86_64 and fails to build
for other architectures. Rather then emitting a compiler error it
would be preferable to only build the test on supported architectures.
Mark proc-empty-vm as a test for x86_64 and customise the Makefile to
build it only when building for this target architecture.
Fixes: 5bc73bb3451b ("proc: test how it holds up with mapping'less process")

Why do you need this? You already have conditional compiles.
Conditionally add proc-empty-vm to TEST_GEN_PROGS like other
tests do.

Same question Andrews asked you. What does it take to get this
to work on other architectures. proc and vm tests should be
arch. agnostic as a rule unless it is absolutely necessary to
have them acrh. aware.
