disable dynamic sized delete support by default
IFUNC relocations don't support our advanced use case (calling
application function or looking up environment variable).
Particularly, it doesn't work on PPC and arm when tcmalloc is linked

https://bugzilla.redhat.com/show_bug.cgi?id=1312462 for more details.
