++#
++# SYNOPSIS
++#
++#   AX_PROG_CC_FOR_BUILD
++#
++# DESCRIPTION
++#
++#   This macro searches for a C compiler that generates native executables,
++#   that is a C compiler that surely is not a cross-compiler. This can be
++#   useful if you have to generate source code at compile-time like for
++#   example GCC does.
++#
++#   The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything
++#   needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).
++#   The value of these variables can be overridden by the user by specifying
++#   a compiler with an environment variable (like you do for standard CC).
++#
++#   It also sets BUILD_EXEEXT and BUILD_OBJEXT to the executable and object
++#   file extensions for the build platform, and GCC_FOR_BUILD to `yes' if
++#   the compiler we found is GCC. All these variables but GCC_FOR_BUILD are
++#   substituted in the Makefile.

+Subject: [PATCH 05/14] Use `target` instead of `host` to detect the C
+ toolchain
+
+When building a cross-compiler, the runtime will run on the target, not
+the host so:
+- set `cross_compiling` by comparing `build` to `target` (rather than to
+  `host`), as this variable will be used later
+- use `target` to set up the tool prefix,
+- as the libtool configuration will configure a `build` to `host`
+  toolchain, temporarily assign `host*` values to `target*` values

+Allow the use of *-*-ocaml or *-*-*-ocaml target triplets to stand for
+freestanding cross-compilers by temporarily rewriting the target OS to
+`none` when generating the canonical target
+
+This allows to use *-*-ocaml and *-*-*-ocaml prefixes for cross-compiler
+specific toolchains, so that all the specific tools (for instance
+aarch64-solo5-ocaml-gcc, etc.) are automatically discovered
