Disable usage of PREF instruction usage by memcpy for MIPS R6. MIPS R6 redefines PREF instruction with smaller offset than ordinary MIPS. However, the memcpy code uses PREF instruction with offsets bigger than +-256 bytes. Malta kernels already disable usage of PREF for memcpy. This was found during adaptation of MIPS R6 for virtual board used by Android emulator.
