I (finally) took a few minutes to look over this.  I really do
not at all like the idea of having each supported os having its
own mostly duplicate config.in files.  Imagine the maintainence
nightmare that would create!  Instead, I want to isolate all OS
specific things into the sysdeps/<OS>/ directories.  To support
things like HURD, create sysdeps/hurd/config.in so that it will
hve a 'define_bool CONFIG_OS_HURD  y' and then use that to hide
things elsewhere as needed, and then add in any HURD specific
applets and options there as well.

Making things work properly will involve moving some things out
of libbb and creating a sysdeps<OS>/libarch.a which will include
any OS specific junk or libc specific adaptions.  Things like
libbb/syscalls.c and libbb/libc5.c would move under
sysdeps/linux.  Presumably, at some point, Linux specific things
like pivot_root might move as well, though I am satisfied with
Linux so I'm not anxious to do that work myself.
