Marius Gerbershagen fb321885db cmp: easier cross-compilation of user code 
The procedure works as follows. First, cross compile ECL itself. In
this step, we dump the configuration of the compiler. This
configuration can then be later restored to put the host compiler into
cross compilation mode using a new option to WITH-COMPILATION-UNIT.

The following changes to the public interface are introduced:

- WITH-COMPILATION-UNIT now takes a new :target keyword
- New functions C:WRITE-TARGET-INFO, C:READ-TARGET-INFO to dump and
  restore the config
- The environment parameters to TYPEP and SUBTYPEP are no longer
  unused. User macros can query type relationships in the target
  environment using these parameters.

Internal changes in the compiler include:

- Target dependent variables in the compiler are defined using a new
  DEFCONFIG macro. C:WRITE-TARGET-INFO simply writes the value of
  these variables to a file.
- The distinction between target types and host types already exists
  in the compiler. In this commit, we just register the target types in
  the compiler environment when we change the compiler configuration.

README.md

ECL stands for Embeddable Common-Lisp. The ECL project aims to produce an implementation of the Common-Lisp language which complies to the ANSI X3J13 definition of the language.

The term embeddable refers to the fact that ECL includes a Lisp to C compiler, which produces libraries (static or dynamic) that can be called from C programs. Furthermore, ECL can produce standalone executables from Lisp code and can itself be linked to your programs as a shared library. It also features an interpreter for situations when a C compiler isn't available.

ECL supports the operating systems Linux, FreeBSD, NetBSD, DragonFly BSD, OpenBSD, Solaris (at least v. 9), Microsoft Windows (MSVC, MinGW and Cygwin) and OSX, running on top of the Intel, Sparc, Alpha, ARM and PowerPC processors. Porting to other architectures should be rather easy.
