[Sbcl-devel] Configurable INSTALL_ROOT / SBCL_HOME

[Nikodemus S. <nik...@ra...>]

The patch at

 http://random-state.net/tmp/install-root.patch

(link good for limited time only) is my current cut at customizing the
intended install-location of SBCL.

It is fundamentally the same as the previous one, except that now that
we have a preliminary installer-builder for Windows it doesn't even
try to install to $PROGRAMFILES.

What it does: the _second_ argument to make.sh (defaulting to
/usr/local) becomes the INSTALL_ROOT, and the default SBCL_HOME
provided by the runtime becomes the INSTALL_ROOT/lib/sbcl/.

Why this is good: 
  sh make.sh "sbcl --no-userinit --no-sysinit" /opt/sbcl/version-xyz 
and the subsequent install.sh does the right thing, and the sbcl is
then startable as /opt/sbcl/version-xyz/bin/sbcl.

Objections to merging this (+ the relevant bits of INSTALL I didn't
write yet)?

(I don't claim this as complete solution: the name of the executable
and core should probably be customizable too, but in case of SBCL I
feel that SBCL_HOME and default install location are more important.)

Two caveats: 

 * As I'm not sure of the intended purpose of the BUILD_ROOT stuff in
   install.sh, I'm not sure I didn't break it.

 * I changed all the Confix.arch-os files to use
 
    CFLAGS += ...

   instead of
   
    CFLAGS = ...

   and while I think I got all the fiddly bits right, I have no way to
   test all the platforms.
