    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 ‘syscall’
    
    Thus replace -std=c11 with -std=gnu11
