Bikeshed: glibc.dl.* or glibc.rtld.*?

Szabolcs, Chung-Lin,

Which tunables namespace should we use for the dynamic loader?

glibc.dl.* (currently proposed by Szabolcs for dl_nns, and surplus static tls).

glibc.rtld.* (currently proposed by Chung-Lin for dynamic_sort=N changes).

dl = dynamic loader/linker
rtld = runtime loader/linker

We have Solaris precedence for using rtld.

We have MacOS precedence for using DL_*

My slight inclination would be to use glibc.rtld.* for everything.

I find rtld immediately identifiable as a loader-related tunable.

While glibc.dl.* might be, or, or something else.
