Subject: uml and -regparm=3

FASTCALL is defined empty in -mm, but UML is not compiled with
-mregparm=3 and so this breaks things (I noticed problems with
rwsem_down_write_failed).

Tried recompiling UML with -mregparm=3, but that resulted in a strange
failure immediately after startup:

|.%Gï¿½.%@: Invalid argument

What's up?
