Alexander Graf 6331cb2165 x86: Include bss subsections in linker script
When we build with -fdata-sections we may end up with bss subsections. Our
linker script explicitly lists only a single consecutive bss section though.

Adapt the statement to also include subsections.

This fixes booting efi-x86_app_defconfig.
