Subject: [PATCH] BuildSetup: __NO_INLINE__ and
 -fno-delete-null-pointer-checks.

 * __NO_INLINE__ fixes the cross-build on some glibc-based systems with
   newer compilers, as it prevents glibc from declaring functions inline
   that we override in libroot_build.
 * We can now enable tree-vrp as long as no-delete-null-pointer-checks
   goes where it used to.
