Situation:
Current glibc have a mechanism called hwcaps. It is not documented and
I was never able to correctly use it anyway. Parts of this mechanism are

There are several problems with that:
- Several hacks to use that for tls.
- Not working.
Proposal:

So? Than please show me how to ask it to enable sse optimized libs and
disable tls.

It is defined as a hwcap internal.

No, this will be fucking slow, thats why my proposal only

So it is unusable if there exists i386, i486 and i686.
