Subject: Android.mk: Fix c11-related build failures

When building with Android.mk we are ending-up with:

    gcc ..... -std=gnu99 .... -std=c11 .... target.o
              ^^^^^^^^^^      ^^^^^^^^
                   |              |
    _______________^_____    _____^___________
     AOSP/KATI GENERATED      MESON GENERATED

Some compilers uses first -std=gnu99 option and ignores second,
which results:

    c99 implicit declaration of function static_assert()

This patch filters-out the first '-std=gnu99' from the cflags obtained
from AOSP/KATI dummy target output to avoid such kind of errors.
