configure does not detect GCC features correctly

[barracuda156]

checking for gcc... /opt/local/bin/gcc-mp-12
checking whether the compiler supports GNU C... no
checking whether /opt/local/bin/gcc-mp-12 accepts -g... no
checking for /opt/local/bin/gcc-mp-12 option to enable C11 features... unsupported
checking for /opt/local/bin/gcc-mp-12 option to enable C99 features... unsupported
checking for /opt/local/bin/gcc-mp-12 option to enable C89 features... unsupported

This is outright wrong – all these should be seen as supported. Compilation is still successful though:

* installing *source* package ‘RoBMA’ ...
** using staged installation
checking for pkg-config... /opt/local/bin/pkg-config
configure: Setting compile and link flags according to pkg-config
configure: Compile flags are -I/opt/local/include/JAGS
configure: Link flags are -L/opt/local/lib -ljags
checking for gcc... /opt/local/bin/gcc-mp-12
checking whether the compiler supports GNU C... no
checking whether /opt/local/bin/gcc-mp-12 accepts -g... no
checking for /opt/local/bin/gcc-mp-12 option to enable C11 features... unsupported
checking for /opt/local/bin/gcc-mp-12 option to enable C99 features... unsupported
checking for /opt/local/bin/gcc-mp-12 option to enable C89 features... unsupported
checking for jags_version in -ljags... yes
configure: creating ./config.status
config.status: creating src/Makevars

Also, older macOS need -D _GLIBCXX_USE_CXX11_ABI=0 flag, otherwise build fails:

I am not really sure which version needs it the last, but some our ports in Macports use it for Darwin < 16.

Hi, sorry for completely forgetting about this. My colleagues and I looked into it when fixing the other issue but we are completely clueless about the cause of this problem.

[barracuda156]

This is a pretty typical issue, reason being: https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html
Not-bleeding-edge OS often need this to be defined to fix building.

I am not really sure if there is a simple way to handle this automatically in R. I know that CMake in Macports takes care of this well enough, so that manual fixing is pretty much never required, while for R packages in Macports I have to add it to fix them. (Does not mean there is no neat solution, I am just unaware of it at the moment.)
