Go back to Travis testing nodejs on Precise - can't seem to avoid
node-gyp incompatibility that does not happens in normal Ubuntu Trusty.
Ruby and Python 3.4 testing corrections for testing on Travis.
Default gcc compiler changes from gcc-4.6.3 to gcc-4.8.4
Migrate target languages except Octave for which there are no equivalent
packages for 3.2 and 4.0
Still test gcc on Precise (errors test-suite only)
Suppresses these for each example/test-suite:
Ignoring executable-hooks-1.3.2 because its extensions are not built. Try: gem pristine executable-hooks --version 1.3.2
Ignoring gem-wrappers-1.2.7 because its extensions are not built. Try: gem pristine gem-wrappers --version 1.2.7
Ignoring nokogiri-1.6.6.2 because its extensions are not built. Try: gem pristine nokogiri --version 1.6.6.2
Use the CCache.html docs instead of the ccache-swig man page.
The yodl2man and yodl2html tools are no longer used and so SWIG no
longer has a dependency on these packages which were required when
building from git.
