pycurl fails to build with the following error:

Using curl-config (libcurl 7.54.0)
Traceback (most recent call last):
  File "./setup.py", line 823, in <module>
    ext = get_extension(sys.argv, split_extension_source=split_extension_source)
  File "./setup.py", line 497, in get_extension
    ext_config = ExtensionConfiguration(argv)

  File "/usr/lib/python2.7/distutils/util.py", line 257, in split_quoted
    if s[end] in string.whitespace: # unescaped, unquoted whitespace: now

The issue is that in C locale string.whitespace contain 0xa0 (160) symbol , nbsp. It shouldn't be there. It comes from strop module. The code in strop module seems to be correct:

    for (c = 0; c < 256; c++) {
        if (isspace(c))
            buf[n++] = c;
    }

and such code works correctly in C locale when compiled separately.
But when in Python it emits additional 160 symbol. So far to workaround an issue we don't import whitespace symbols from strop module.
