    x86/build: Build compressed x86 kernels as PIE when !CONFIG_RELOCATABLE as well · a980ce35
    H.J. Lu authored
    Since the bootloader may load the compressed x86 kernel at any address,
    it should always be built as PIE, not just when CONFIG_RELOCATABLE=y.
    
    Otherwise, linker in binutils 2.27 will optimize GOT load into the
    absolute address when building the compressed x86 kernel as a non-PIE
    executable.
