[boost] boost/1.71: bootstrap fails on ubuntu

Package and Environment Details

• Package Name/Version: boost/1.71
• Operating System+version: Linux Ubuntu 16.04/19.04
• Compiler+version: GCC 5.4.0/CLang 8
• Conan version: conan 1.18.0
• Python version: Python 3.6.x/3.7.x

Steps to reproduce

Starting with 1.71 the build now fail on all our ubuntu-based systems. The same systems can build 1.70 just fine. CentOS 7 is fine as well.

The command: conan create /tmp/conanfile.py local/testing -o boost:bzip2=False -o boost:namespace=boost_ns -o boost:namespace_alias=True -o boost:magic_autolink=True --build outdated

On a side note - as seen in the log two of the patches are no longer necessary and should be removed.

Unknown toolset: cc

You can specify the toolset as the argument, i.e.:
    ./build.sh gcc

Toolsets supported by this script are:
    acc, clang, como, gcc, intel-darwin, intel-linux, kcc, kylix, mipspro,
    pathscale, pgi, qcc, sun, sunpro, tru64cxx, vacpp

For any toolset you can override the path to the compiler with the CXX
environment variable. You can also use additional flags for the compiler
with the CXXFLAGS environment variable.

A special toolset; cxx, is available which is used as a fallback when a more
specific toolset is not found and the cxx command is detected. The 'cxx'
toolset will use the CXX, CXXFLAGS, and LIBS environment variables, if present.

Similarly, the cross-cxx toolset is available for cross-compiling by using the
BUILD_CXX, BUILD_CXXFLAGS, and BUILD_LDFLAGS environment variables to compile
binaries that will be executed on the build system. This allows CXX etc. to be
set for cross-compilers to be propagated to subprocesses.

[SSE4]

the code that was failing has been completely removed in #1016, so these errors aren’t going to happen any more - we’re not doing bootstrap during the boost build. there is another bug (#1122) and pending PR #1124 that fixes b2 invocation on certain systems. I’ll keep it open for a while, but once #1124 merged, pls retest and let me know (or just test changes locally).

[firewave]

I was able to get it to work with 1.70.0 by removing the toolset parameter from https://github.com/conan-io/conan-center-index/blob/8a07dd95d9479f8998f77fdcd5d68a334b763778/recipes/boost/all/conanfile.py#L351

But this will obviously break #192 again…
