Unsupported relocation against r0

Today I'm building mono-2.8 for ArchlinuxPPC, and I get this error from the assembler:

{standard input}: Assembler messages:

{standard input}:26505: Error: unsupported relocation against r0

make: *** [libmonoruntimesgen_la-sgen-gc.lo] Error 1

The solution is modifying CFLAGS:

export CFLAGS="$CFLAGS -Xassembler -mregnames" 

Have a nice day
