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.
See GCC bug report:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77311
