commit dcbe79bd630b6176eac7214834234218de744f2a

build-sys: Set C language standard to gnu11
Per glibc feature_test_macros(7), setting compiler flags to
-std=c11 (or any c* variant like c99) enforces strict ANSI
mode.
Enforcing strict ANSI makes all declarations under _GNU_SOURCE
unavailable. This leads to build warnings in the form of:
warning: implicit declaration of function âsyscallâ
Thus replace -std=c11 with -std=gnu11
