Subject: [PATCH] BaseTools/Source/C: Remove CPU architecture assumptions

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3308

The EDK II Build Specifications do not restrict the set of
CPU architectures that can be supported.  Remove places in
the EDK II that assume a fixed set of CPU architectures.

Remove build breaks in the following tools when a check against
a fixed set of CPU architectures is made.
