This reverts commit 3d12ddae.

The commit was instroducing errors in compilation or at runtime.

Compilation error were like (for cmake in Debian 8 machine):
[ 99%] Built target CTestLib
[100%] Built target ctest
Install the project...
bin/cmake: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by bin/cmake)
bin/cmake: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by bin/cmake)
Makefile:72: recipe for target 'install' failed
make: *** [install] Error 1
cmake: Command 'set -e;make  install' returned non-zero exit status 2
cmake: Compilation error. The package is left as is at /srv/slapgrid/slappart61/srv/runner/shared/cmake/9fc4b0e8f4f03ce17eb7ef43525d2238__compile__/cmake-3.7.2 where you can inspect what went wrong.

Runtime errors were like (for mariadb in Debian 9):

We'd prefer ld to always take LD_RUN_PATH into account, even if any
rpath is specified in the command-line. We could actually change the
wrapper this way but it would not be consistent with the case where
the SR is built with system gcc.

Patches taken from https://github.com/spack/spack/pull/15403

Commit f355e0af didn't work because
GCC building ignores LDFLAGS when linking libgfortran.so
whereas the latter does not even need zlib and would be linked to
system zlib (if it exists) for nothing.

In our case, there seems to be no zlib code inside the installed files.

Mostly useful for components that are built with cmake.

c++ already exists. cmake searches for c++ in the same folder as it found cc.

aspell-en-dictionary, groonga-normalizer-mysql, file-msooxml, apache-antiloris are not shareable, they write files in other parts.

As currently it fallbacks to system's gettext

The mpc and mpfr component already in the component/binutils.cfg. Remove the duplicate ones.

Update: the test passed. @rafael

also drop non-existing '--with-nm' option.

drop gcc-multiarch.patch that is no longer needed.
add ppl-0.11-gcc-4.9.patch to compile with gcc-4.9.

zc.buildout >= 1.6.0-dev-SlapOS-013 automatically rebuilds parts whose referring parts are modified.

that is required to compile varnish VCL in runtime.
