Haiku buildtools contains old in-tree softwares

[miqlas]

Why Haiku using old-old autoconf and libtool in the buildtools ( ​https://git.haiku-os.org/buildtools )? I does not mean the "legacy" folder!

• Our autoconf is 2.61, but the latest version is 2.69 (it is a 6 years long span between the two version)
• Our libtool is 1.5.2, while the latest is 2.4.6 (almost 10 years long span)
• Our isl is 1 year old.

I swapped these softwares to the latest version, and tried to make a test build on OSX, but i got some errors at configuring binutils (i have no problem with the original in-tree version). So it seems, there is some not-upstreamed Haiku specific patches and mods in these softwares. IT would be great to upstream these changes (if any), and update the in-tree softwares to the latest version.

These are used only to build the buildtools, as you can check from the Haiku command line:

~> autoconf --version
autoconf (GNU Autoconf) 2.69
~> libtool --version
libtool (GNU libtool) 2.4.2

We update these only when needed by a new gcc version, I think. Since they are only used to build the compiler, it doesn't really matter to keep them up to date.

You can see the changes by looking at each specific folder: ​https://cgit.haiku-os.org/buildtools/log/autoconf In the case of autoconf it seems there are not a lot of changes (just a single one).

So, no changes needed here then; buildtools can do what it likes.
