An application might want to use C11 features. The user would assume that setting `CFLAGS=-std=gnu11` in the Makefile would work. It does not since the board's Makefile.include shadows the `-std` flag. This patch removes the `-std=gnu99` from the various Makefile.includes, and sets the flag in the common Makefile.include of RIOT instead. If an `-std` flag was provided by an earlier Makefile (the application, the board, or the CPU [whilst only the former one should]), then no additional flag is set. It is first tested if the supplied compiler understands `-std=gnu99`, then `-std=c99`.
