As Mr. Millard suggested, this goes into /etc/make.conf
BINARY_ALIAS=
I've tried BINARY_ALIAS= c++=clang++50
BINARY_ALIAS= /usr/local/bin/c++=/usr/local/bin/clang++50
/usr/local/llvm50/bin/c++=/usr/local/llvm50/bin/clang-5.0
and the second example without the first "/" before "usr"
There are two different targets from c++ in two directories (as in the
examples; in /usr/local/llvm50/bin/, clang++ links to clang-5.0). I've tried
this with the examples above, and it didn't work. There's more to BINARY_ALIAS.
The soft links I've used for both directories, ln -s clang++50 c++, and ln -s
clang-5.0 c++, have worked for compiling rust. It was mentioned in a bug
report, but I'm emailing the maintainers of rust.
Thank you
