scripts: Add sortextable to sort the kernel's exception table. Using this build-time sort saves time booting as we don't have to burn cycles sorting the exception table.

scripts/sortextable: Handle relative entries, and other cleanups x86 is now using relative rather than absolute addresses in its exception table, so we add a sorter for these.

ARM: 7568/1: Sort exception table at compile time Add the ARM machine identifier to sortextable and select the config option so that we can sort the exception table at compile time. sortextable relies on a section named __ex_table existing in the vmlinux, but ARM's linker script places the exception table in the data section. Give the exception table its own section so that sortextable can find it. This allows us to skip the sorting step during boot.
