The extra __ suffix/prefixed ones are ARM specific. They seems to be
introduced from day 1 in glibc, without any obvious reason.
They're just aliases - __end__, _bss_end__, etc are identical to _end

If you want to cater for GNU/Hurd - the following three should be
listed as well.

_fbss
_fdata
_ftext

I haven't had time to read through the patches, although +1 on the overall idea.
Will try to get to it sometime tomorrow.
