lang/compilers support for MacOS

I am trying to build several compiler packages (clang, llvm, libLLVM, gcc5, gcc6) on MacOS (10.11.6, Xcode 8.1 (8B62)) from pkgsrc-2016Q4 and am running into issues. Are any of these packages known to work on MacOS?

One problem I ran into was apparent lack of mode support in the native libtool (see https://gist.github.com/jperkin/8dbdc72540d76583c3f4). Applying that patch helped, but did not solve all the problems.

Here are the issues I ran into (after the patch):

lang/llvm (a clang dependency): Compiling failed with the following error:

[ 4%] Linking CXX static library ../libLLVMSupport.a
libtool: unrecognized option `-static'
libtool: Try `libtool --help' for more information.
*** Error code 1

lang/libLLVM: Compiling failed with the following error:

[ 6%] Linking CXX static library ../libLLVMSupport.a
libtool: unrecognized option `-static'
libtool: Try `libtool --help' for more information.
*** Error code 1

lang/gcc48: Compiles fine.

lang/gcc49: Compiles fine.

lang/gcc5: Compiling failed with the following error:

Any help on this is welcome. Thanks a lot.
