In order to prepare the transition to autoconf, this commit moves the
configuration Makefile out of the config directory which will disappear
and gives it the name it will have once intstalled, namely Makefile.config.
Previously, `ocamlc`, `ocamlopt`, `ocamllex`, and `ocamldep` defaulted
to the bytecode versions of the tools. However, there is normally no
advantage to the bytecode versions if the native-code versions are
available, except in unusual circumstances. Instead, install the
native-code versions without the `.opt` suffix. They are still
installed with the `.opt` suffix for backwards compatibility. Finally,
install the bytecode versions with the `.byte` suffix, and build
native-code versions of tools that are not currently built in native
code.
Also, remove some duplication in tools/Makefile.shared.
Supersedes GPR #512.
Since, Makefile.tools is used by both the testsuite and the manual, it
should be moved to the first common ancestor of the two subdirectories:
the root directory.
Note: also remove testsuite/lib/empty and use noinit when invoking the
ocaml interpreter.
