Do. Not. Do. That. Again. Ever.

There are people on the list that do *not* have broadband, and will suffer
like in hell just to get a message they are not even remotely interested
in. If you need to send such a huge file again, please put it on a website
and just put the pointer in the mail.

It's hidden behind the EXPERIMENTAL, and it requires using daily snapshots
of uClibc (as no release with NPTL has been made yet).

You mean you want to run the uClibc test-suite?
So, no, crosstool-NG (not crossng, btw) does not yet have support for that.
Doing so would require a complex setup (eg. a real board, with an account
with valid pre-exchanged ssh keys, etc...), so it's beyond the scope of
crosstool-NG.

What crosstool-NG can do, is install the test-suite along-side the toolchain
so you can easily run it. That's what is currently done for gcc. Then it is
up to you to prepare the proper setup and run the test-suite.

What do you mean by "the new dynamic linker"? Are you referring to gold?
It's not supported.

gold is currently limited to x86 (AFAIK), so it'd require a kludge to offer
the option only for x86. That's doable, but I did not have the time to look
at it. You're welcome to provide a patch, of course! ;-)
