The script were failing to generating the proof but it was continuing anyway.
  the set -e forces the script exit.

  This diff don't cause error since bash isn't run with -e but makes write_backup_proof useless basically.

Some phones with Android 12+ disconnects from
5G networks which don't support IMS. Therefore
we add minimal IMS support in this commit (even
though we don't actually need it's features).

Only Amarisoft >= 2024-05-02 support launching
lteims without root privilege, so if Amarisoft
version is older IMS is disabled and we inform
the user so in the connection parameters.

For this to work, SIM cards config needs to be
modified, impu and impi must be for instance:
impu: 001010000001312,
impi: 001010000001312@ims.mnc001.mcc001.3gppnetwork.org

 - pycrypto does not seem used (because it does not work on py3 with buildout3)
 - cns.recipe.symlink and PyRSS2Gen versions are defined in stack/slapos.cfg

Revert eb1b1a41 to avoid the use of
`fPIC` flag as it is a "contagious" build option.

To not face the build error "relocation R_X86_64_32 against
.rodata.str1.8 can not be used when making a shared object; recompile
with -fPIC" while building a shared library without fPIC flag, `gcc` is
compiled with `-enable-default-pie` flag (which is a compilation option
used for `gcc` binaries provided by Debian by example, see `gcc -v`).

Since slapos package provides gettext, it is not necessary to build
gettext here. Also slapos package's gettext commands such as msgfmt
may not work with libraries built by a software release, thus remove
LD_LIBRARY_PATH.

With newer setuptools that is coming via nexedi/slapos!1550 (44.1.1 -> 67.8.0)
we will need a fix from setuptools-dso 2.10 to handle `python setup develop` well:

Previously with setutools-dso 2.9 and setuptools 67.8.0 built shared libraries were not
copied back into the working tree upon develop install which made anything
using pygolang to fail as e.g.

    $ ../bin/gpython
    Traceback (most recent call last):
      File ".../../bin/gpython", line 20, in <module>
        sys.exit(gpython.main())
      File ".../pygolang/gpython/__init__.py", line 456, in main
        pymain(argv, init)
      File ".../pygolang/gpython/__init__.py", line 223, in pymain
        init()
      File ".../pygolang/gpython/__init__.py", line 447, in init
        import golang
      File ".../pygolang/golang/__init__.py", line 41, in <module>
        from golang._gopath import gimport  # make gimport available from golang
      File ".../pygolang/golang/_gopath.py", line 65, in <module>
        from golang import sync
      File ".../pygolang/golang/sync.py", line 36, in <module>
        from golang._sync import \
    ImportError: liblibgolang.so.0.1: cannot open shared object file: No such file or directory

and https://github.com/mdavidsaver/setuptools_dso/commit/2fdf75f2 for details.

P.S. NOTE that changing version of a setup-egg required egg currently does
_not_ force a rebuild. In other words pushing this change into testnodes won't
make pygolang t o be rebuilt at all. I think this is simply a bug in
slapos.buildout to fix.

This is done as an alternative to the patch in !1580, as the last
version is already patched.

without this change, configure would use openssl lib for MD5, sha256sum, ...
if openssl development files are present on the system.

Previously, zstd support was only compiled if zstlib was installed in
the system.

This especially brings support for systems where 'model name' is not
present in /proc/cpuinfo

the previous version was failing like this if lib64 doesn't exist:

libcap: Command 'set -e;cd /opt/slapgrid/shared/libcap/4d09237abd7cb34117fccc1d3c3bc862
[ -d lib64 ] && ln -s lib64 lib' returned non-zero exit status 1
