 To go back to the error: the configure stage was looking for
 `/Applications/Xcode.app/Contents/Developer/usr/bin/llvm-gcc-4.2`. A quick
 search on Google suggests that `llvm-gcc-4.2` is quite outdated. So I
 don't know why configure was looking for it. On my system, I have these
 `gcc` as part of the command line tools, but no `llvm-gcc-4.2`:

 {{{
 $ /Applications/Xcode.app/Contents/Developer/usr/bin/gcc
 Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr
 --with-gxx-include-dir=/usr/include/c++/4.2.1
 Apple LLVM version 8.0.0 (clang-800.0.42.1)
 Target: x86_64-apple-darwin16.3.0
 Thread model: posix
 InstalledDir:
 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
 }}}

 And `g++` in the same directory is just a symlink to `gcc`
