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.
