New stdarg.h and varargs.h based on arm and i386 versions.

Use __builtin_va_* instead of hand written code in va-sh.h that uses
LHS casts.  Slightly worse code is generated by gcc 3.3.3, but LHS
casts are outlawed in gcc 3.3.6 and gcc 4.

Build-tested on hpcsh (le) and mmeye (be), run-tested on hpcsh.
