buildenv: actually strip unused cpuid functionality

Despite the macro message says, that cpuid functionality was stripped
it was still partially preset and wasn't used anyhow.

-# SYNOPSIS
-#
-#   AX_GCC_X86_CPUID(OP)
-#
-# DESCRIPTION
-#
-#   On Pentium and later x86 processors, with gcc or a compiler that has a
-#   compatible syntax for inline assembly instructions, run a small program
-#   that executes the cpuid instruction with input OP. This can be used to
-#   detect the CPU type.
-#
-#   On output, the values of the eax, ebx, ecx, and edx registers are stored
-#   as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
-#   ax_cv_gcc_x86_cpuid_OP.
-#
-#   If the cpuid instruction fails (because you are running a
-#   cross-compiler, or because you are not using gcc, or because you are on
-#   a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
-#   is set to the string "unknown".
-#
-#   This macro mainly exists to be used in AX_GCC_ARCHFLAG.
