+*** Link-time optimization with clang doesn't work on Fedora 20.

+As of May 2014, Fedora 20 has broken LLVMgold.so plugin support in clang
+(tested with clang-3.4-6.fc20) - `clang --print-file-name=LLVMgold.so'
+prints `LLVMgold.so' instead of full path to plugin shared library, and
+`clang -flto' is unable to find the plugin with the following error:

+/bin/ld: error: /usr/bin/../lib/LLVMgold.so: could not load plugin library:
+/usr/bin/../lib/LLVMgold.so: cannot open shared object file: No such file

+The only way to avoid this is to build your own clang from source code
+repositories, as described at http://clang.llvm.org/get_started.html.

-The Emacs configuration process allows you to configure the
-build environment so that you can build emacs in a directory
-outside of the distribution tree.  When installing Emacs from an
-out-of-tree build directory on Solaris, you may need to use GNU
-make.  The make programs bundled with Solaris support the VPATH
-macro but use it differently from the way the VPATH macro is
-used by GNU make.  The differences will cause the "make install"
-step to fail, leaving you with an incomplete emacs
-installation.  GNU make is available in /usr/sfw/bin on Solaris
-10 and can be installed as /opt/sfw/bin/gmake from the Solaris 9
-Software Companion CDROM.
-
-The problems due to the VPATH processing differences affect only
-out of tree builds so, if you are on a Solaris installation
-without GNU make, you can install Emacs completely by installing
-from a build environment using the original emacs distribution tree.
