Enhance setting the minimum kernel version glibc will run against.
Ideally, eglibc should also benefit for that, but the current code does not set it.

Original patch from H.J. Lu, as reported there:

http://www.nabble.com/PATCH:-Use-short-for-fnstsw-td14775171.html

fnstsw stores 16bit into %ax. The upper 16bit of %eax is unchanged.

The new assembler (binutils-2.18.50.0.4 and up) will disallow "fnstsw %eax".
