[PATCH libX11 1/2] config: Fix architecture check for OS/2 to skip nios2 cpu

[Dan Nicholson]

The OS/2 platform requires some utility functions as well as having a
non-32 bit wchar_t. Fix the configure check so that it doesn't also
affect the nios2 cpu, which wouldn't influence these operating system
issues.
