Please consider adding C++14 and perhaps c++17 as well. At least tbb
(wip/threadingbuildingblocks) has switch-cases for C++11 and C++14
building - I would like to configure the flavor with USE_LANGUAGES value.

c11 is needed value as well.

It's reasonable to switch - behind the scenes - to g++11, g++14, g++17
and gnu11. This will address a common issue with alloca(3) from our
libc, which cannot work properly and the GNU builtin won't be picked up.
