The version of boost.m4 initially included in cc-tool has an issue
with gcc5 (one of its tests fails due to the first change described in [1]
"Preprocessor issues").
This was fixed upstream (boost.m4 project) in Nov 2014 [2].
We add the latest commit [3] of upstream boost.m4 plus a patch from github PR
[4] to add detection for gcc 5.1.
