arm: make __bss_start and __bss_end__ compiler-generated
Turn __bss_start and __bss_end__ from linker-generated to compiler-generated symbols, causing relocations for these symbols to change type, from R_ARM_ABS32 to R_ARM_RELATIVE. This should have no functional impact, as it affects references to __bss_start and __bss_end__ only before relocation, and no such references are done.
