Therefore it pulls in getopt() from libc/libcygwin, but since optarg is not prefixed with

thus resulting in multiple definitions thereof.

Rather than requiring them of a certain version, detect if they are present
(and have sufficient version) and select an appropriate companion tool
otherwise. The reason is that, for example, most recent gettext requires
automake 1.15, but the newest available CentOS has 1.13. Hence, the option
to "upgrade your system" does not apply, and the warning comment above
the companion tools is rather scary.
With this approach, it will work out of the box - either by using the host's
tools, or by building them as needed. Note that the user can still change
the setting in the config.
While there, propagate the new version checking macro to awk/bash/host binutils,
and switch from --with-foo=xxx to officially blessed FOO=xxx: the latter
does not require checking for bogus values (i.e., --with-foo, --without-foo)
and AC_PROG_* macros recognize the corresponding settings without further

This follows the trend set by 1*.sh scripts that configure ISL, GMP,
MPFR, CLooG, etc. Building with shared libraries presents all kinds
of problems:
- The shared libraries need to be installed into ${CT_PREFIX_DIR}.
- The binaries linked against companion libs need to have proper
RPATH, or they're looking for shared libs in
.build/${CT_PREFIX}/buildtools/lib.
- All libraries must agree as to whether they're built shared,
static, or both. Otherwise, gettext tries to link in static libncurses.a
into a shared library and fails (since libncurses was compiled without
the -fPIC switch and hence contains relocations that cannot be handled
in a shared library).
So this fixes the current mess. If we decide to re-enable building
the companion libs shared, we should probably make this dependent on
a separate suboption of CT_STATIC_TOOLCHAIN.

To build uClibc correctly we need correct endianness selected in the

CT_ARCH_ENDIAN_CFLAG so that -m{big,little}-endian don't get added to

via addToolVersion.sh. Import newest versions of the companion tools.
One non-trivial change is the handling of make versions. Existing code
was not handling make companion tool as described (see the previous
commit). However, since most modern systems have make 4.x, that previous
commit made crosstool-ng always build make as a companion tool.
This traces back to the commit dd15c93 from 2014. That commit's log message
says that actually it was 3.81 which broke the build for certain component
(it was originally breaking eglibc, but I noticed it was breaking current
glibc on powerpc64), and introduced an option to force using 3.81 by
"components that really need it". It looks like in 2.5 years we haven't
seen any such components that really need make 3.81, and (given that make
has already had a few releases since 3.81) we're unlikely to see them
in the future.
Hence, the configure check is changed from "exactly 3.81" to "3.81 or newer".
In its current form, configure will accept make 3.80+, and will not require
make as a companion tool for 3.81+. We might want to bump the latter check
to even newer version given the claim from dd15c93. Killed
COMP_TOOLS_make_3_81_NEEDED.
Anyway, I retained 3.81 just in case; ditto for m4 1.14.3, autoconf 2.65
and automake 1.11.1.

The referenced commit replaced 'make' with '${make}' everywhere. This is
wrong for at least the utilities that we may build as companion tools
(make, libtool): this will always invoke the version detected by configure
by supplying the absolute path. In other words, the wrappers in
.build/tools/bin are not fallbacks - they are either temporary (in case
a respective companion tool is built) or permanent redirectors.
This is the reason why the PATH= has .build/*/buildtools/bin at higher
precedence than .build/tools/bin; the latter has the versions detected by
configure and the former has the versions built as companion tools.
Revert the rest of the gang (grep/sed/...) for consistency. After all,
we may decide to supply some of them as well (awk, for instance).

Commit 6f8e89cb5c broke that option.
Since ${make} points to /usr/bin/make, making the symlink from gmake
to /usr/bin/make is obviously the wrong decision. gmake should link to
our (old-versioned) self-built make.
