R-alpha: Re unified shell script

Some time ago there was the suggestion to add a PLATFORM subdir level
for bin (and eventually the library subdirs with `binaries'), and the
idea to have the shell wrapper automagically call the right binary.

I mentioned that one might be able to use the shell variables OSTYPE and
HOSTTYPE for that, noticing however that e.g on my Debian Linux/GNU/ix86

		bash	tcsh
OSTYPE		Linux	linux
HOSTTYPE	i386	i386-linux

Hmm ... It seems (a colleague just checked that) that these variables
are not POSIX either, and hence I'd say rather useless for our purpose.

In the absence of a reliable run-time possibility to determine the
current platform, it seems to be natural to use `platform' as obtained
at compile-time for possibly distinguishing the various binaries etc,
and leave it at the discretion of the sysadmin to ensure that the R
script in the path calls the right binary.

If I am missing something obvious, please let me know.
