stella: fix bug when compiling with PPC altivec vectorization
PPC altivec vectorization triggers a bug when compiling with -std=c++11
because "bool" is redefined in altivec.h.
src/emucore/Event.hxx:112:23: error: cannot convert ‘bool’ to ‘__vector(4) __bool int’ in assignment
myKeyTable[i] = false;
^
Acording to a bug report in GCC [1], "You need to use -std=g++11 or
undefine bool after the include of altivec.h as context sensitive
keywords is not part of the C++11 standard".
So let's compile with -std=gnu++11 by default.
Tested on ARM, x86 and PPC.
