[Nouveau] [PATCH xf86-video-nouveau 09/17] config: remove unrequired AC_HEADER_STDC

[Rhys Kidd]

Autoconf says:
"This macro is obsolescent, as current systems have conforming
header files. New programs need not use this macro".

Was previously required to ensure the system has C header files conforming
to ANSI C89 (ISO C90). Specifically, this macro checks for stdlib.h,
stdarg.h, string.h, and float.h.

This autoconf option was used to provide conditional fallback support
via defined STDC_HEADERS.

xf86-video-nouveau does not do so, so this macro is obsolete and unused,
so let's drop it.
