Remove AC_FUNC_MEMCMP check from configure.in

Browse source 
As far as I can tell, AC_FUNC_MEMCMP is useless for us. It checks for
some obscure `memcmp' bugs on some ancient systems, and gives us a
chance to provide a working `memcmp'. Since we're not shipping with a
local copy of a `memcmp', it makes no difference whether or not the test
fails. And when cross-compiling, the test automatically fails, as it
tries to compile and run a test program:

    checking for working memcmp... no

Quoting autoconf docs: ``This macro is obsolescent, as current systems
have a working memcmp. New programs need not use this macro.''
