Rather than having to specify or omit -DBYTESWAP in the Makefile
fragment for each system we can detect whether the system requires
byte swapping based on the __BYTE_ORDER__ C preprocessor definition.
Update CMakeLists.txt to account for this as well.
This no longer had anything to do with profiling and was
only doing some defines for the switch case block addresses,
which we no longer need since there's no longer optional
asm generated for them.
This is the old way that releases were built and isn't relevant
today. It made a variety of assumptions about how things were
linked and allowed for the user to re-link an executable, but
that isn't something we need to do any longer.
This doesn't yet remove the checksum, ldechecksum, and related
scripts.
