Change subject: systemc: Move systemc disabling checks to SConsopts.
......................................................................
systemc: Move systemc disabling checks to SConsopts.
This will ensure that the value of USE_SYSTEMC is consistent throughout
the build. It also has the side effect that USE_SYSTEMC can be forced
to a particular value if you're confident you know what you're doing
and want to override these checks.
