JFYI, __bss_start, _edata, _end, _fini, _init, _exit are not symbols
from libnl, but symbols related to the dynamic linking infrastructure
and are (largely) implementation-specific. In addition, "libnl_3" is
the prior symvers symbol, also not a C function/variable. Don't just
take everything `nm` outputs at face value :)

You never need to fumble with the visibility of these, or list them
in any symbol file. As such, removing them from the .sym files does
not constitute an ABI change.
