[meta-clang] [PATCH] nonclangable: Add python3

[meta-clang] [PATCH] nonclangable: Add python3

[Maxime Jourdan]

While python3 will build "successfully" with clang,
it will silently discard a few modules in the process:

Python build finished successfully!
The necessary bits to build these optional modules were not found:
_bz2                  _curses_panel         _dbm
_gdbm                 _lzma                 _sqlite3
_ssl                  nis                   readline
zlib

The lack of these modules will generate empty packages
which can later break do_rootfs.

while this is fine, I would appreciate if you can delve a bit and see
why these tests
would fail with Clang and pass with gcc. It could be simple bugs in
python itself where
it assumes compiler == gcc

Hi Khem,

Sure I'll take a look. In the meantime this documents the issue.
