Hi Harald,

I've just uncovered a rather nasty issue with dracut, where for no 
apparent reason a (multithreaded) program was crashing.
Reason being here that libpthread _requires_ libgcc_s when any 
program is using 'pthread_cancel'. When the library isn't present
any of those calls will generate a SIGABRT.
Nasty.

Best would be to pull libgcc_s in always when libpthread is 
required. But that would be some library detection magic.
Can you fix this up?

Cheers,

Hannes
