Michael Kerrisk ed44de1f5e ld.so.8: Simplify language around conferring capabilities
The statement "conferring permitted or effective capabilities"
to the process is somewhat redundant. Binaries with capabilities
confer capabilities only to those process capability sets, so it's
simpler to just say"confers capabilities to the process".

Carlos O'Donell bbba55c221 ld.so.8: Expand DT_RUNPATH details.
ld.so.8: Expand DT_RUNPATH details.

Every 3 years we get asked why DT_RUNPATH doesn't work like DT_RPATH.
The most recent question was here:
https://www.sourceware.org/ml/libc-help/2017-06/msg00013.html

We need to expand the description of DT_RUNPATH to cover this situation
and explain that the DT_RUNPATH entries apply only to the immediate
DT_NEEDED, not that of another, say dlopen'd child object.

Applies to master.

Michael Kerrisk a3a72ad210 ld.so.8: LD_BIND_NOT has effect only for function symbols
As far as I can tell from testing and a short read of the glibc
source code, LD_BIND_NOT has an effect only for function symbols.
This is consistent also with the Solaris documentation, which
says:

    When the runtime linker performs a function relocation, it
    rewrites data associated with the functions .plt so that any
    subsequent calls will go directly to the function. The
    environment variable LD_BIND_NOT can be set to any value to
    prevent this data update. By using this variable together
    with the debugging request for detailed bindings, you can
    get a complete runtime account of all function binding.

Test case:

$ cat prog.c

int
main(int argc, char *argv[])
{
    for (;;) {
	sleep(1);
	optind = 0;
    }

    exit(EXIT_SUCCESS);
}
$ cc prog.c

And then in the run below, in each loop, we see repeated resolutions
only for the function symbol, sleep() (and not for optind).
