- disable tests on 32bit archs

- update to 2.11.1
* Fix a bug that prevented looking up a key after an attribute
({{ data.items[1:] }}) in an async template
* Drop support for Python 2.6, 3.3, and 3.4. This will be the last version
to support Python 2.7 and 3.5.
* Added a new ChainableUndefined class to support getitem and getattr
on an undefined object.
* Allow {%+ syntax (with NOP behavior) when lstrip_blocks is disabled.
* Added a default parameter for the map filter.
* Exclude environment globals from meta.find_undeclared_variables().
* Float literals can be written with scientific notation, like 2.56e-3.
* Int and float literals can be written with the ‘_’ separator
for legibility, like 12_345.
* Fix a bug causing deadlocks in LRUCache.setdefault
* The trim filter takes an optional string of characters to trim.
* A new jinja2.ext.debug extension adds a {% debug %} tag to quickly dump
the current context and available filters and tests.
* Lexing templates with large amounts of whitespace is much faster.
* Parentheses around comparisons are preserved, so {{ 2 * (3 < 5) }} outputs
“2” instead of “False”.
* Add new boolean, false, true, integer and float tests.
* The environment’s finalize function is only applied to the output of expressions
(constant or not), not static template data.
* When providing multiple paths to FileSystemLoader, a template can have
the same name as a directory.
* Always return Undefined when omitting the else clause in a {{ 'foo' if bar }}
expression, regardless of the environment’s undefined class. Omitting
