Subject: [PATCH] Makefile: Suppress array-bounds error
The array-bounds error is triggered now in cases where it was silent
before, causing errors like:
```
plat/imx/imx8m/hab.c: In function 'imx_hab_handler':
plat/imx/imx8m/hab.c:64:57: error: array subscript 0 is outside array bounds of 'uint32_t[0]' {aka 'unsigned int[]'} [-Werror=array-bounds]
64 | #define HAB_RVT_CHECK_TARGET_ARM64 ((unsigned long)*(uint32_t *)(HAB_RVT_BASE + 0x18))
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
The error is a false-positive and is entered as a bug [1]. The problem
is fixed partially in GCC 12 and fully in GCC 13 [2].
The partial fix does not work here because the constant addresses used
are less than the 4kB boundary chosen for the partial fix, so suppress
the error until GCC is upgraded to 13.
