Enable shared libraries

Enable shared libraries support in llvm39 for use in the Mesa ports. Lightly tested with Xorg and GNOME 3 desktop, with the dri llvm based software render driver. This might be applied to llvm38 but I'm planning on skipping that version in the Mesa ports and go straight to llvm39. So I don't really care about llvm38.

The patch is needed otherwise libLLVM-3.9.so is only 4k big and has no symbols. While here patch in DragonFly support too.

Forgot to mention where I got my info from. The Cmake macro's are listed here: http://llvm.org/docs/CMake.html#llvm-specific-variables . Use of BUILD_SHARED_LIBS is not recommended.

cleanup devel/llvm39 Makefile

As I was also working on this issue at the same time, I accumulated some fixes to quiet most of portlint's complaints. This patch is just the cleanups:

correct placement of PKGNAMESUFFIX
convert spaces to tabs
remove blank lines
qwk -> ${AWK}
sed -> ${SED}

Committed both diffs.  Thanks!
Comment 6 Dan Nelson 2016-11-17 03:25:03 UTC
Now that libLLVM.so works, another option to consider adding is -DLLVM_LINK_LLVM_DYLIB=ON . This will make all the binaries link against libLLVM.so instead of the static versions, and shrinks the install size by over 50%.

  Upgrade to 3.9.1.

  Link programs dynamicaly.  This reduces package size by over 400MB on
