There are only binaries on a download page and I don't believe binary 
downloads pages any more, so I checked out from SVN repository. I 
confirm it is able to compile C and C++ code and link it statically with 
musl libc and clang libc++, but I have this trouble with using it to 
recompile itself. It compiles about 2 hours on my box so it is quite 
hard to experiment with environment variables just to find out it was 
still built with GCC.
