[PATCH] Fix insta-reboot with "i386: Relocatable kernel support"

Commit 968de4f02621db35b8ae5239c8cfc6664fb872d8 ("i386: Relocatable
kernel support") caused problems for people with old binutils versions
that didn't mark ".text.*" sections automatically allocated.

So we should use .section command to specifically mark .text.head
section as AX (allocatable and executable) to solve the problem.

This should be unnecessary with binutils 2.15 and later, which is
already three years old, but it doesn't hurt supporting older toolchains
where possible.
