Add the 'lto' option to enable building with link time optimization
by adding '-flto' to both CFLAGS and CXXFLAGS.  The 'lto' option can
be specificed both in the PKGBUILD or by setting the default in
makepkg.conf.

TODO:
 - strip LTO symbols from distributed .a/.o files.
   e.g. https://bugzilla.redhat.com/attachment.cgi?id=1650804&action=diff
- provide helper script to adjust old autoconf files for LTO support(?)
   e.g. https://bugzilla.redhat.com/attachment.cgi?id=1650843&action=diff
   Not sure this should be part of makepkg or distribution tools.
In Arch, this script could be distributed as a makepkg template.  As
makepkg-template places a copy of the templated code in the PKGBUILD,
users would not need devtools installed to use the PKGBUILD.

I'm thinking this is the best approach.  Opinions?
