[tex-live] TL platforms vs. dpkg-architecture

Hi Andreas,

Indeed, there is no relation, or not that I know off. Our (TL) platform
is more or less the output config.guess that gets massaged.

For details see
	TLUtils::platform*
in particular
	TLUtils::platform_name
that does the massaging from config.gues to TL:

Example code there:
  # armv6l-unknown-linux-gnueabihf -> armhf-linux (RPi)
  # armv7l-unknown-linux-gnueabi   -> armel-linux (Android)
  if ($CPU =~ /^arm/) {
    $CPU = $guessed_platform =~ /hf$/ ? "armhf" : "armel";
  }

What do you need that for? What is the aim for it? Debian anyway
use self-compiled, so the names as used by TL are not very important.

Do you want to use one installation with various archs, and
geenrate the correct link automatically by querying dpkg?

You could probably use the perl code for that:
	perl -I /path/to/tl/2016/tlpkg/ -e '$::installerdir = "/path/to/tl/2016"; use TeXLive::TLUtils; print TeXLive::TLUtils::platform_name(TeXLive::TLUtils::platform()), "\n"; '

which gives in my case
	x86_64-linux

I guess because config.guess is doing that.

Hope that helps
