[PATCH] Fix PR55599/sanitizer by disabling static libasan on darwin

[Alexander Potapenko]

In fact nothing prevents GCC from having a linkable static ASan runtime.
The reason for the static library being unusable is not in the dynamic
runtime itself, but in mach_override not working well with other GCC
libraries (it is unable to parse some function prologues). Because
ASan is transitioning to the dynamic runtime in LLVM, it's unlikely
we'll put any effort into fixing mach_override.
