 remove hardcoded gcc optimization flags
 This is necessary in order to make DEB_BUILD_OPTIONS=noopt work as expected.
 .
 Note that the hack on llvm-config --cxxflags is not absolutely needed, because
 the -O2 that it brings come before the -O0 brought by dpkg-buildflags. But I
 leave it for clarity.

 do not give a soname to libjulia-release.so
 Otherwise the fact that this SONAME is unversioned confuses dpkg-shlibdeps and
 dh_makeshlibs. And we don't want a versioned SONAME for now, the API is not
 stabilized.

 drop version number from system load path
 This is unnecessary since this path is managed by dpkg/apt. Moreover, it would
 make transitions to higher versions needlessly complicated.

 julia requires sse2 on i386
 This patch adds an explicit error message if the CPU does not support SSE2.
 The CPU features are queried using the x86 CPUID opcode. The wrapper function
 __get_cpuid() is provided by GCC and Clang. See <cpuid.h> for the list of
 supported CPU extension flags.

 use packaged mathjax instead of the online version
 This patch can probably be dropped when #739300 is fixed.
 Note that this patch goes in tandem with several commands in d/rules, and with
 d/julia-doc.links

 use libjs-modernizr package inplace of external link.
 This resolves a potential privacy breach by fetching data from
 an external website at runtime, as indicated in a lintian hint.
 The script is included as a static file by sphinx-rtd-theme.

 on the sidebar font of the Julia language documentation.

 do not query ldconfig for library sonames
 This patch modifies the dynamic loading of shared libraries
 to not query ldconfig for library sonames when ccall() is
 invoked for a library name without an extension.
 .
 By default, when ccall() is invoked for the shared library
 libfoo, it tries to load libfoo.so; if that fails, it queries
 ldconfig and picks a matching libfoo.so.SOVERSION. Since a
 machine can have multiple installed versions of the same
 library, this may result in unpredictable behaviour when
 ccall() loads a library version with an incompatible ABI.
 .
 For the libraries used by Base, the Debian package provides
 symbolic links lib*.so => lib*.so.SOVERSION in the private
 library path for Julia, which ensures that Julia loads exactly
 those library versions that were used for building the package.
 .
 For external packages installed using Pkg.add() that have an
 unversioned library dependency, users need to install the
 corresponding lib*-dev package that provides lib*.so.
