Since switching to C++11 the NaCL build was disabled.
This re-enables the ARM configuration which uses a
more recent version of gcc. This means that that NaCl
code paths will at least be test until we can find a way
to re-enable the X86 build.
Some CCLog message contained trailing newlines which
made the logs hard to read on many platforms. The solution
here is to stip trailing newlines on those platforms, and also
to remove the newlines from the existing log messages.
