This commit does four things: * Adds "pb.ss" and "pb.c", which implement a portable bytecode backend and interpreter that is intended for bootstrapping. A single set of pb bootfiles can support bootstrapping on all platforms --- as long as the C compiler supports a 64-bit integer type. The pb machine supports foreign calls for only a small set of recognized prototypes, and it does not support foriegn callables. Use `./configure --pb` to build the pb variant. * Changes the kernel's casts between `ptr` and `void*` types. In a pb build, the `ptr` type can be a 64-bit integer type while `void*` is a 32-bit pointer type, so casts must go through an intermediate integer type. * Adjusts the compiler to accomodate run-time-determined endianness. Making the compiler agnostic to word size is not practical, but only a few pieces depend on the target machine's endianness, and those can generally be deferred to a run-time choice of byte-based operations. The one exception is that ftype bit fields are not allowed unless accompanied by an explicit endianness declaration. * Start reducing duplication among platform-specific makefiles. For example, `Mf-ta6osx` chains to `Mf-a6osx` to avoid repeating most of it. A lot more can be done here. original commit: 97533fa9d8b8400b0dc1a890768c7d30c91257e0
