    [PATCH] x86: Drop cc-options call for all options supported in gcc 3.2+ · c8fdd247
    Andi Kleen authored
    The kernel only supports gcc 3.2+ now so it doesn't make sense
    anymore to explicitely check for options this compiler version
    already has.
    This actually fixes a bug. The -mprefered-stack-boundary check
    never worked because gcc rightly complains
      CC      arch/i386/kernel/asm-offsets.s
    cc1: -mpreferred-stack-boundary=2 is not between 4 and 12
    We just never saw the error because of cc-options.
    I changed it to 4 to actually work.
    Tested by compiling i386 and x86-64 defconfig with gcc 3.2.
    Should speed up the build time a tiny bit and improve
    stack usage on i386 slightly.
