Revert "[PATCH] x86: Drop cc-options call for all options supported in gcc 3.2+"
This reverts commit c8fdd247. It turns out the kernel was correct, and the gcc complaint was a gcc bug. The preferred stack boundary is expressed not in bytes, but in the the log2() of the preferred boundary, so "-mpreferred-stack-boundary=2" is in fact exactly what we want, but a gcc that is compiled for x86-64 will consider it an error (because the 64-bit calling sequence says that the stack should be 16-byte aligned) even if we are then using "-m32" to generate 32-bit code.
