Boot linker scripts were not ready for this. This fix adds *(.text.*), *(.data.*) etc patterns directly after corresponding *(.text), *(.data) etc patterns in all boot linker scripts. This may be unnecessary, but I want to be function and data section-clean in all linker scripts, including boot ones.
