The patch is attached again to simplify the reproduction.

I took the useldt.h from the glibc 2.2.93 from the RedHat 8.0 source RPM 
package and changed only that code, which was really necessary to change.
Some other changes like NATIVE_SELF -> THREAD_SELF, include order and so on
were made too. Now all test-programs of ngpt work again on RedHat and really
use the new stuff of the GLIBC useldt.h header file.

I don't really know what I did here. All my changes were the direct result of
compiler errors and a bit look around for the right place of the symbol.
So someone with more deeper knowledge should check all this.

And remember, you also need my autoconf 2.53 fix, to even start the compilation
on RedHet 8.0 (if you use autoconf at all, like I have to because of other
problems).

Bye, Uwe
