[Mesa-dev] [PATCH kmscube] meson.build: Do not set c_std

[Fabio Estevam]

When building kmscube in Buildroot for ARM the following
errors are seen:

../common.c: In function 'get_time_ns':
../common.c:376:18: error: storage size of 'tv' isn't known
  struct timespec tv;
                  ^~
../common.c:377:2: warning: implicit declaration of function 'clock_gettime'; did you mean 'localtime'? [-Wimplicit-function-declaration]
  clock_gettime(CLOCK_MONOTONIC, &tv);
  ^~~~~~~~~~~~~
  localtime
../common.c:377:16: error: 'CLOCK_MONOTONIC' undeclared (first use in this function)
  clock_gettime(CLOCK_MONOTONIC, &tv);

Fix it by using the default for each compiler on every platform instead.

Inspired by this gst-plugins-good commit:
