Fix SCons linking error when building for Multi ISA.
When building for Multi ISA the link command throws:
'argument list too long' error since the list string being
pass to the linker exceeds the ARG_MAX value. The solution is to
split the object list into two distinct static libraries and have them
link back together.
Prohibit unknown variable use.
The script now checks for unknown parameters.
