Remove cpuid.h configure tests. 

There are configure tests for the cpuid.h header for x86 / x86_64.
GCC 4.3 and later install this header, so those tests are obsolete.
This patch removes them.

Tested for x86_64 and x86 (testsuite, and that installed shared
libraries are unchanged by the patch).

	* sysdeps/i386/configure.ac (cpuid.h): Do not test for header.
	* sysdeps/i386/configure: Regenerated.
	* sysdeps/x86_64/configure.ac (cpuid.h): Do not test for header.
	* sysdeps/x86_64/configure: Regenerated.
