This gets enabled by default in gcc-14 and complains everywhere where we
use assert() on an expression that is always true (i.e. using
`int x[static 2]` in function declaration, etc.):

Disabling this selectively only for asserts is a bit painful, since the
option is not available in all compilers, and it'd need to be handled in
the EFI stuff as well.
