Remove obsolescent AC_HEADER_STDC
Autoconf 2.59d (released in 2006) [1] started promoting several macros
as not relevant for newer systems anymore, including the `AC_HEADER_STDC`.
This macro checks if given system has C89 compliant header files such
as <string.h>, <stdlib.h>, <stdarg.h>, <float.h>,... and defines the
`STDC_HEADERS` symbol [2]. Case is that current systems should be well
supported with at least C89 standard headers [3].
Given headers are still additionally checked with the `AC_PROG_CC`
macro, yet not needed anyway.
For cmake build system this applies similarly and the manual custom
check of the standard headers can be removed likewise.
