Ubuntu Mate 16.04

Any ideas?

Silly workaround:
remove BREAKPOINT in error.cpp

[TheJJ]

Maybe you can implement the correct BREAKPOINT asm for powerpc. The x86 asm should only be used on x86, anyway. This should be an easy task to do.

@TheJJ #890 (comment)
would probably need to add a case:

#elif __powerpc
#define BREAKPOINT asm("tw 31,0,0")

which should unconditionally cause a program interrupt
