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.

- fixed handling of bintar, rpm, pkg make files

- fixed a bug in the fasl representation and reading of mutually
recursive ftypes where one of the members of the cycle is the
parent of another, which manifested in the fasl reader raising
bogus "incompatible record type" exceptions. (The bug could also
affect other record-type descriptors with cycles involving parent
rtds and "extra" fields.) object files created before this fix
are incompatible with builds with this fix, and objects files
created after this fix are incompatible builds without this fix.

- added a cast to eliminate warnings in c/number.c
- fixed bug in Windows version of directory-separator-predicate in s/6.ss when path-* procedures are passed a path that is not a string.
- fixed bug in s/cp0.ss on Windows with $foreign-wchar?.
- fixed spelling of non-existent

files that no longer exist, which was getting in the way of creating links
for files that do exist. Also updated the build batch file for Windows to
compile the nanopass framework separately before building the rest of the
scheme compiler and libraries.
