439cab379e Require xz to be present
Some software starts to adopt xz-only distribution (strace,
gcc-linaro, ...). Better that than deal with cryptic errors like
"cannot find strace-.tar.bz2".

2dae1cf816 Require GNU sed
After much struggling with macos (BSD) sed and even getting everything
work in crosstool-ng itself, I had to abandon that because some
components rely on GNU syntax. Specifically, GNU libc uses '/.../{H;g}'
(note absense of the separator after 'g').

So, revert the -r/-E detection and check for sed's being of GNU origin.
MacOS people, sorry, but you'd have to install GNU sed.

7bcf18bfab Determine whether -E/-r option selects extended regexp
... and then use the right option. See the note in scripts/functions
on where we should use ${foo} and where just 'foo'; this boils down to
whether we can expect the build tools override to be in effect (e.g. in
the actual build scripts) or not (i.e. outside of scripts/build).
While running in scripts/functions, or in scripts/crosstool-NG.sh the
build tools override directory (.build/tools/bin) may have not been
set up (yet, or at all).

Also, modify the installed scripts (populate, xldd) accordingly.

7a94c81e5b Rework configure logic wrt GNU autotools
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
modifications. For now, I kept --with-foo=, if only to complain and steer
people to the new way. To be cleaned up after a release.

87bfd55b3b Give companion tools some love.
Allow selection of make/m4/... version. Support imports of new versions
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.

6c49a232a8 configure: Correctly search for tinfo for kconfig
I previously thought that tinfo could only be a link to libncurses in
modern ncurses installations. I was wrong.

Now we check for ncurses, then check for tinfo. If tinfo is a link to
ncurses, it is then not required to link against. But if libtinfo is
providing tgetent, and not libncurses, then we must add it to LIBS as
well.

Also, kconfig shouldn't hardcode -lncurses, it should use what is in
$(LIBS).

0e45cdf624 autoconf: Update version numbering
This change removes the static .version file, and moves to using the git
tag as the version number, the change number if the current commit is
newer then the latest tag, and '-dirty' if there are changes to the git
repository since the last commit that are uncommitted.

This helps us in the troubleshooting process to identify if the user is:
* using a released version (i.e.: 1.21.0)
* using a clone from git (i.e.: 1.21.0-29-13e14f)
* using a clone from git with local uncommitted changes (i.e.: 1.21.0-29-13e14f-dirty)
