branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

hostinfo_unix.cpp:1695:37: error: range-based 'for' loops are not allowed in C++98 mode
         for (const string &ignore : ignore_list) {

Adding -std=c++11 to CXXFLAGS is done in _MAKE_OPTS due to the Makefiles
not passing CXXFLAGS from _CONV_ENV down to client/Makefile.

This is needed since bump to version 7.18.1 in commit
fe79fba3fd52cd6445c5a1d90629c94605c93519 and
https://github.com/BOINC/boinc/commit/ed70369c091923addf5a8d64bed92c0417e91e07
