Supercollider fails to build

[Felipe Sateler]

OK, so we have more build failures, but this time different on
different architectures:

1. Arm*: qreal is not double but float. Patch is in the repository.
2. PowerPc64: Undefined variable order. It seems that there is a bogus
call in line 255 of
external_libraries/boost_lockfree/boost/atomic/detail/gcc-ppc.hpp, but
I'm not sure.
3. ia64: missing ifdef case in
external_libraries/nova-simd/benchmarks/perf_counter.hpp (starting at
line 466). I don't know how to fix this.
4. all big-endian archs: Typo in
external_libraries/boost_endian/boost/integer/endian.hpp:285. It seems
like an extra ) crept in in the least-tested #ifdef path. Patch in the
repository too

Dan, could you forward these issues upsteam?
