[Buildroot] [git commit] mongrel2: add upstream patch to fix symbol conflict

commit: http://git.buildroot.net/buildroot/commit/?id=1ed2e40497365941cb4b4f486e9ec19ec034fedb
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The symbol 'max_align_t', defined in the mongrel2 sources
(src/mem/align.h), is also defined in one of the standard headers in
some toolchains (the ones based on GCC 5+ apparently).

This conflict has been solved upstream, and a new version (1.10.0)
containing the fix has been released already, so this backported patch
may be dropped in the future when mongrel2 gets a version bump.

Fixes:
