## Versions of gcc >= 4.9.0 require special version of 'ar' and 'ranlib' for
## link-time optimizations to work properly.
##
## From https://gcc.gnu.org/gcc-4.9/changes.html:
##
##     When using a linker plugin, compiling with the -flto option now
##     generates slim objects files (.o) which only contain intermediate
##     language representation for LTO. Use -ffat-lto-objects to create
##     files which contain additionally the object code. To generate
##     static libraries suitable for LTO processing, use gcc-ar and
##     gcc-ranlib; to list symbols from a slim object file use
##     gcc-nm. (Requires that ar, ranlib and nm have been compiled with
##     plugin support.)
