Subject: [PATCH] gfx,direct: Aboid usng VLAs and printf formats
VLAs are flagged by clang when using non-POD types, therefore replace
the usage with alloca which is exact same allocation on stack
__attribute__((__format__ (__printf__))) is not portable as used here
therefore disable the check for clang here, we lose no functionality
