x86, build: Disable -fPIE when compiling with CONFIG_CC_STACKPROTECTOR=y

The arch/x86/Makefile uses scripts/gcc-x86_$(BITS)-has-stack-protector.sh
to check if cc1 supports -fstack-protector.  When -fPIE is passed to cc1,
these scripts fail causing stack protection to be disabled even when it
is available.

This fix is similar to commit c47efe5548abbf53c2f66e06dcb46183b11d6b22
