That can't be right.

" cpu
     The type of processor used on the system. (...)

     A somewhat freeform field which indicates the manufacturer of the system. (...)"

It's manufacturer of the system, not of the CPU.
Note "used on the system", therefore cpu != system.  And "system"
is really a broad term.  AFAIK, it's really a freeform field in
practice, so you should be able to put anything there.  For example,
if one takes xilink's toolchain sources (the gpl bits), fork / patch
them for some reason, and build / distribute them oneself, one
might want to legitimately change the manufacturer field to
avoid confusion.
System, in this case, is the FPGA, manufactured by Xilinx.

Or "system" is a board that includes an FPGA manufactured by Xilinx, yet assembled and sold by some other vendor, that happens to decide to add some spice or to do some incompatible changes to Xilink's version of the toolchain. In the case of an intel x86 cpu, what you call the "system"? That answer to that should reveal that your interpretation of system cannot be the only one possible.

Perhaps you are arguing that the patch should be rejected, so that the current behavior that only "microblaze-xilinx-gnu" would is accepted, and the change would make "microblaze-megacorp-gnu" also match. If so, then I agree that this would be an undesirable consequence.
