meson/cc: Disable memory-allocating builtins
Disable the memory allocating builtins as they may cause unexpected behavior
with our framework. They *may* get optimized out in favor of a register or
stack variable, making them effectively local.
Local variables do not play well with longjmp, which we use for fixtures
and subtests.
