Hi,

This week I worked on packaging crosstool-ng 1.23 for Debian using 
existing work.

I found that some dependencies are missing from the binary package so 
`ct-ng build` works correctly with minimal base system (like m4, wget).

I also added patches:
- 0001-Disable-MAKELEVEL-check.patch:
    An alternative to setting MAKELEVEL=0 inside debian/rules.
    This patch comments out the check of MAKELEVEL inside `Makefile.in`.

- 0002-Makefile.in-remove-recursive-part.patch:
    This patch fix the infinite recursion issue. I should probably share 
this into crosstool-ng and put the following text into the patch 
description :).
    The issue is that Debian dh run `make -n` which give `nrR` inside 
MAKEFLAGS and the `filter` function only matches whole words.
    Using `findstring` replaces every occurrences of the given text, 
making the assumption that no long options will contain `rR` or `Rr`.

- 0003-Backport-commit-Fix-debuild-warnings-errors.patch:
    This patch backports the commit [1] to fix lintian warning and errors.

I added installation of the bash completion script into 
/usr/share/bash-completion/completions (which is the new directory 
replacing /etc/bash_completion.d/).

I've added a watch file which use [4] and checks the gpg signature 
against `debian/upstream/signing-key.asc`.
The signing-key.asc file contains public keys of Alexey Neyman and Bryan 
Hundven (not sure if they are all the needed signatures).

I added a autopkgtest test to build a `arm-unknown-eabi` toolchain to 
check that the built package is working properly.

I put my package sources on github [2] with a travis configuration to:
- Build on travis a schroot of unstable (as travis use old ubuntu releases)
- Use this schroot to run sbuild inside which also run lintian and 
autopkgtest.
- Not that relevant but travis-ci also upload the built package to 
bintray when building a tag.

I use git-buildpackage to manage the source package.
My workflow is documented at `debian/README.source`.

Due to the length of the toolchain building and limitation of travis 
build max duration, I only test one toolchain build (arm-unknown-eabi).
FYI, Travis sbuild logs are available here [3].

I'm not sure about my medium/long term availability to maintain this 
package, but I hope what I have done can help to get crosstool-ng into 
Debian :)
