Python 2.7 Linux wheel without ucs4 support

[fluffyGator]

Could a Python 2.7, Linux wheel be supported that doesn't have the --enable-unicode=ucs4 (-cp27mu-) requirement. Most Python Linux installs aren't usually compiled with this flag (e.g. Canopy Python package) in my experience. The OSX 2.7 wheel works well with just the --enable-unicode=ucs2 flag, so I suspect it isn't critical.

@dursch00 We are using pyenv for building this package, I don't know how we should change the unicode configure flag. I'll investigate closely, but this is likely to be the root cause of https://discourse.mozilla.org/t/unable-to-install-deepspeech-on-centos-6-9/26023

Ok, that was faster than I expected, I found that on some github issue:

PYTHON_CONFIGURE_OPTS="--enable-unicode=ucs4" pyenv install

I'm wondering if there's value in more than cp27-m and cp27-mu variants ?

@dursch00 This should be an easy task, mostly duplicating the current 2.7 builds and just tweaking do_deepspeech_python_build to add the configure flags. If you like, you can try a PR :)

Thanks for quick response.. One thing I just noticed that may adversely affect this that tensorflow also doesn't have a cp27m option for Linux ....

I don't think it's such a big deal, there is still value for us in providing the deepspeech python bindings for those systems.
