When I wrote the patch above, I didn't know that AX_GCC_X86_CPUID macro does not guarantee that its result is always 4*8-digit. Actually, result of AX_GCC_X86_CPUID does not contain leading zeroes and number of digits may vary.
As a result, I broke AX_GCC_ARCHFLAG for most of AMD processors and older Intel processors.
This patch will fix this issue by changing case patterns.

To make sure this issue is fixed correctly, I tested the script using CPUID dumps available at

Sorry for breaking a macro and I hope this fix will be helpful.
