[PATCH v1 1/2] scripts/mtest2make.py: export all-%s-targets variable and use it

["Alex Bennée" <alex.bennee@linaro.org>]

There are some places where the conditional makefile support is the
simplest solution. Now we don't expose CONFIG_TCG as a variable create
a new one that can be checked for the check-help output.

As check-tcg is a PHONY target we re-use check-softfloat to gate that
as well.
