Subject: [PATCH] meson: Always use -fno-strict-aliasing and
 -fno-strict-overflow

SPA does not respect the C strict aliasing rules at all, so any code
that uses it must be built with -fno-strict-aliasing.  Furthermore,
there is code in SPA that compares pointers that point to different
objects, so -fno-strict-overflow is also needed.
