nhmall 1cb5dc0460 work around ubuntu 20.10 build issue ...

NetHack was trying to suppress warn_unused_result
in include/tradstdc.h, by defining warn_unused_result
to an empty string. That began causing a build error
in a system-supplied header file cdefs.h
when using 20.10 ubuntu impish.

Try skipping that in tradstdc.h for any linux, unless
the NetHack build defines GCC_URWARN to force it into
play.
