libc-glibc: remove 2.3.6

This is an obsolete version which is no longer used by any sample (the only
user, the ia64 sample, has been removed).

It also makes the code path a bit complex, with twists just to accomodate
that version. Removing the version will make those twists go away, and
will ease commonalisation of glibc and eglibc in the future (hopefully!).

    10 There are two ways you can use crosstool-NG:
    11  - build and install it, then get rid of the sources like you'd do for most
    12    programs,
    13  - or only build it and run from the source directory.
    14 
    15 The former should be used if you got crosstool-NG from a packaged tarball, see
    16 "Install method", below, while the latter is most useful for developpers that
    17 use a clone of the repository, and want to submit patches, see "The Hacker's
    18 way", below.
    19 
    20 
    21 Install method |
    22 ---------------+
    23 
    24 If you go for the install, then you just follow the classical, but yet easy
    25 ./configure way:
    26   ./configure --prefix=/some/place
    27   make
    28   make install
    29   export PATH="${PATH}:/some/place/bin"
    30 
    31 You can then get rid of crosstool-NG source. Next create a directory to serve
    32 as a working place, cd in there and run:
    33   ct-ng help
    34 
    35 See below for complete usage.
    36 
    37 
    38 The Hacker's way |
    39 -----------------+
    40 
    41 If you go the hacker's way, then the usage is a bit different, although very
    42 simple:
    43   ./configure --local
    44   make
    45 
    46 Now, *do not* remove crosstool-NG sources. They are needed to run crosstool-NG!
    47 Stay in the directory holding the sources, and run:
    48   ./ct-ng help
    49 
    50 See below for complete usage.
    51 
    52 Now, provided you used a clone of the repository, you can send me your changes.
    53 See the section titled CONTRIBUTING, below, for how to submit changees.
    54 
    55 
    56 Preparing for packaging |
    57 ------------------------+
    58 
    59 If you plan on packaging crosstool-NG, you surely don't want to install it
    60 in your root file system. The install procedure of crosstool-NG honors the
    61 DESTDIR variable:
    62 
    63   ./configure --prefix=/usr
    64   make
    65   make DESTDIR=/packaging/place install
    66 
    67 
    68 Shell completion |
    69 -----------------+
    70 
    71 crosstool-NG comes with a shell script fragment that defines bash-compatible
    72 completion. That shell fragment is currently not installed automatically, but
    73 this is planned.
    74 
    75 To install the shell script fragment, you have two options:
    76  - install system-wide, most probably by copying ct-ng.comp into
    77    /etc/bash_completion.d/
    78  - install for a single user, by copying ct-ng.comp into ${HOME}/ and
    79    sourcing this file from your ${HOME}/.bashrc
    80 
    81 
    82 Contributed code |
    83 -----------------+
    84 
    85 Some people contibuted code that couldn't get merged for various reasons. This
    86 code is available as lzma-compressed patches, in the contrib/ sub-directory.
    87 These patches are to be applied to the source of crosstool-NG, prior to
    88 installing, using something like the following:
    89   lzcat contrib/foobar.patch.lzma |patch -p1
    90 
    91 There is no guarantee that a particuliar contribution applies to the current
    92 version of crosstool-ng, or that it will work at all. Use contributions at
    93 your own risk.
