debug: Fix __bug_table[] in arch linker scripts
The kbuild test robot reported this build failure on a number
of architectures:
> make.cross ARCH=arm
> lib/lib.a(bug.o): In function `find_bug':
> >> lib/bug.c:135: undefined reference to `__start___bug_table'
> >> lib/bug.c:135: undefined reference to `__stop___bug_table'
Caused by:
19d436268dde ("debug: Add _ONCE() logic to report_bug()")
Which moved the BUG_TABLE from RO_DATA_SECTION() to RW_DATA_SECTION(),
but a number of architectures don't use RW_DATA_SECTION(), so they
ended up with no __bug_table[] ...
Ideally all those would use RW_DATA_SECTION() in their linker scripts,
but that's for another day.
