A GCC bug is triggered when the compiler is run with an optimization level '-Os/-O2/-O3' for the Blackfin architecture: ``` error: unable to find a register to spill in class 'CCREGS' ``` Workaround this bug by forcing an optimization level of '-O1' when building libxslt for the Blackfin architecture.
