i386: Delete old machine dependent files
- The files in the i386 directory have been moved to common x86 directories by FreeBSD:
- freebsd/sys/x86/x86/legacy.c
- freebsd/sys/x86/include/machine/legacyvar.h
- freebsd/sys/x86/include/machine/specialreg.h
- Add header files in rtemsbsd directory to direct compiler to new files
