Then make the use of the type (or all of prelinking) depending on
this.  If a new architecture is added it'll have the same problem.
Define _DL_HAVE_NO_ELF_MACHINE_RELA or and test for it in dl-conflict.

I understand this.  But we should delay making such changes until they
are ready to be incorporated.  The missing _rela function is an issue
unrelated to not being able to implement prelinking and therefore
should be handled.  With this change you can use the current code
until it is proven which method will work for MIPS.
