[lm-sensors] 2.10.1: No rule to make target `asm/io.h',

I found some posts along these lines on the web. However, I take that
you never saw this warning, because our code reads:

/* To keep glibc2 happy */
#if defined(__GLIBC__) && __GLIBC__ = 2 && __GLIBC_MINOR__ >= 0
#include <sys/io.h>
#else
#include <asm/io.h>
#endif

So it should look for sys/io.h rather than asm/io.h. It does for me.
I suspect that the test on __GLIBC__ somehow fails for you. Can you
please give a try to the following program?

--- 8< ---
#include <stdio.h>

int main()
{
	printf("__GLIBC__ = %d\n", __GLIBC__);
	printf("__GLIBC_MINOR__ = %d\n", __GLIBC_MINOR__);
	return 0;
}
--- 8< ---

$ gcc -Wall -W test_glibc.c -o test_glibc

I expect some surprise on your FC6 system.

That being said the test above looks bogus to me, the test on
__GLIBC_MINOR__ is useless as far as I can see, and the test will break
on GLIBC 3 for sure.
