The reasoning is incorrect.  The dependency chain of a port is:

- Upstream GCC needs upstream Binutils
- Upstream Linux kernel needs upstream GCC
- Upstream Glibc needs upstream Linux kernel

So the removal of IA64 from the Linux kernel means we should remove it
from Glibc, but you cannot reversely traverse the dependency chain and
claim it should be removed from GCC or Binutils.

Note that I don't mean IA64 shouldn't be removed.  I just mean the
reasoning is incorrect, the conclusion may be correct or not.
