objinfo_helper: slightly generalise usage message

Use argv[0] rather than hardcoding "objinfo_helper".

That way the message is accurate whether there is a ".exe" extension or not.
 (commit: 92331f8)

Make ext_exe public in the configuration module of the compiler
 (commit: 16006d5)

objinfo: take possible .exe extension into account when calling objinfo_helper
 (commit: 758ab7d)

tools/ocamlmktop.ml: make use of the configured extension of executalbes

Before this commit, the name of the compiler to use (ocamlc or ocamlc.exe)
was determined base on the OS type. This commit replaces this by
a mere string concatenation of "ocamlc" and the configured extension
for executable files.

This introduces a dependency of tools/ocamlmktop on the compiler's
configuration module.

Fix distclean rule

Commit 13786d7d122 accidentally removed a file twice.

Makefile: introduce the CMPBYT variable
 (commit: 1c158f4)

Makefile: avoid one recursive invocation of make

The `core` target can depend on `coldstart` rather than invoking
`$(MAKE) coldstart` as its first command.

lex/Makefile: simplification
 (commit: b7d8a97)

ocamltest: improve the way executable file extension is determined

Use the EXE build variable rather than OS type to determine the
extension of executable files
 (commit: a50d177)

tools/Makefile: stop considering ocamldep and cvt_emit as precious
 (commit: 41e4dc1)

Add the $(EXE) suffix to all programs at build rather than install time

This commit touches neither boot/ocamlc nor boot/ocamllex

It has the side-effect of fixing the cleanup rules which did not use the
$(EXE) extension when removing a file although it was produced with the
$(EXE) extension.
 (commit: bdd9ca3)

Build system: simplify installation rules

Now that programs are built with their $(EXE) suffix, their installation
rules can be simplified a bit because most of the programs get installed
under the name they have been built with.
