pointcloud does not respect Macports compiler setting, which breaks the build

[barracuda156]

Firstly, it needs C++11 standard set, otherwise build fails straightaway with cc1plus: error: unrecognized command line option "-std=c++11".

However, with compiler.cxx_standard set, it still picks a wrong compiler in a middle of the build:

Unsurprisingly, this fails.

pointcloud uses for parts of its build, configuration from PostgreSQL, derived by including pg_config --pgxs (the configurations of interest is ultimately read from ${prefix}/lib/postgresql15/pgxs/src/Makefile.global). According to Port health at ​https://ports.macports.org/port/pg15-pgpointcloud/details/, this is working out fine for all OS with results. The C++ standard part is surely easily implementable, but I have no idea of how to address the second part of the ticket.

Well, postgresql15 does not require C++11, AFAIK, so it builds fine with gcc-4.2. We can probably switch it to use modern GCC, if that is the only way.

16. S. Port health is useless for old systems, since no buildbots for 10.5, no buildbots for powerpc and no buildbots using libstdc++.
