Many gnu packages are changed to supply tar.gz and tar.xz and no more
tar.bz2
The proposed change is to
- build xz just after bzip2 on toolchain [[BR]]
- any package after that in the build order could use tar.xz [[BR]]
To not change the tar prerequiste, those packages using tar.xz or tar.lzma
has to use a pipe to tar to open the package like [[BR]]
xz -d < $(DL_FILE) | tar xf -
The gain is as follow [[BR]]
1308 autoconf-2.65.tar.bz2 [[BR]]
10292 coreutils-8.4.tar.gz [[BR]]
1736 diffutils-2.9.tar.gz [[BR]]
2316 gawk-3.1.7.tar.bz2 [[BR]]
1280 grep-2.6.1.tar.gz [[BR]]
892 gzip-1.4.tar.gz [[BR]]
1104 m4-1.4.14.tar.bz2 [[BR]]
304 patch-2.6.1.tar.gz [[BR]]
2300 libtool-2.2.6b.tar.gz [[BR]]
2692 texinfo-4.13a.tar.gz [[BR]]

So that spare 11 MB where you should withdraw xz size (1 MB) and xz
building time.
coreutils, diffutils, grep , gzip , libtools, textinfo are no more
available as tar.bz2 (patch is still available as tar.bz2)
More gain is reachable using binutils and glibc tar.xz but that suppose
the build host support that format or build xz first and another time
later just for the toolchain. That probably could wait until kernel.org
distribute xz package ( such discussion has been opened in february by
kernel.org admin )
