I am currently engaged in compiling Linux-ppc source tree using a CC other
than GCC.

May I ask you _why_ you want to do that?!?

The mind fairly boggles. Anyway, once upon a time, current wasn't kept in
a register but in memory. And if r2 won't do, just pick another register
and tell the compiler not to touch it. Hope your compiler of choice has
such a thing as --fixed-r2 ...

And if you want to use kgdb to debug your kernel, gdb knows that current is r2...
