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.
A recent somewhat related example of this is the addition of the
w64 vendor to distinguish the mingw-w64 toolchain from the
mingw.org (vendor == pc) toolchain.
Quoting the whole description this time:
A somewhat freeform field which indicates the manufacturer of the system. This is often simply `unknown'. Other common strings are `pc' for an IBM PC compatible system, or the name of a workstation vendor, such as `sun'. "
Emphasis on "somewhat freeform".
