[Mesa-dev] [PATCH kmscube v2] meson.build: Change c_std to gnu99

[Fabio Estevam]

Since commit 301a556b8ece ("add fps reporting") the <time.h> header
is included, which causes build failures with c99 extension on ARM32:

../common.c: In function 'get_time_ns':
../common.c:376:18: error: storage size of 'tv' isn't known
  struct timespec tv;
                  ^~
../common.c:377:16: error: 'CLOCK_MONOTONIC' undeclared (first use in this function)
  clock_gettime(CLOCK_MONOTONIC, &tv);

Change c_std to gnu99 to fix the build error as explained at:
https://gcc-help.gcc.gnu.narkive.com/8xCaKI6r/problem-with-struct-timespec-and-c99-standard
 
c99 has been used since commit 6cbd03ab9406 ("Makefile.am: Add -std=c99 to
CFLAGS") to fix the following mips64el build failure:

"cube-tex.c:230:2: note: use option -std=c99 or -std=gnu99 to compile your code"

Use c_std=gnu99 to make both mips64el and ARM32 happy.
