 Supercollider is FTBFS in ppc, with the following message:
 {{{
 /tmp/cc01sBbv.s: Assembler messages:
 /tmp/cc01sBbv.s:7543: Error: operand out of range (0x000000000001cd58 is
 not between 0xffffffffffff8000 and 0x0000000000007ffc)
 /tmp/cc01sBbv.s:7545: Error: operand out of range (0x000000000001cd50 is
 not between 0xffffffffffff8000 and 0x0000000000007ffc)
 }}}
 The generated assembler relevant section:
 {{{
 #APP
 # 1160 "/usr/include/boost/atomic/detail/gcc-ppc.hpp" 1
 lwarx 7,0,11
 cmpw 7, 9
 bne- 2f
 stwcx. 10,0,11
 bne- 2f
 addi 8,0,1
 }}}

 The faulty lines are the bne- instructions. These instructions are
 manually written in gcc-ppc.hpp.

 Reported as Debian bug #723117.
