SubjectAT_EXECFN not useful
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I've just removed the support for AT_EXECFN again from glibc. The
information isn't useful because the path name isn't normalized. I.e.,
it's not the actual binary path if symlinks are followed during the
resolution. This makes it unusable for the $ORIGIN handling. This is
on top of the problem with relative paths.

Unless somebody has another use case where this is useful I suggest
removing AT_EXECFN support again. It's just superfluous work and memory
use.

Of course I wouldn't object to a real implementation which always gives
me the full, normalized path name of the executable...
