so i tried a third build method, gcc 3.4, and that built it fine but UML crashed during bootup:

rip 0x6020fd92 0x6020fd92 <txInit+306>
txInit is in JFS.
but at least i could build UML. (this is all with pristine -git)
So i checked the patch below. And it built fine, and boo^H^Hcrashed just like it did before:
- PTRACE_FAULTINFO...not found - PTRACE_LDT...not found UML running in SKAS0 mode Segmentation fault
so i guess this is the way to go?
