Run ar with --plugin for LTO 11 test
Objects built with -fno-fat-lto-objects (the default for gcc-4.9) have
no normal symbols, except things like __gnu_lto_slim. These useless
symbols are the ones put into the archive index, and of course nothing
references them so no objects are extracted by the linker. Running
ar with --plugin changes ar behaviour to put the lto symbols into the
archive index.

--plugin path_to_gcc/liblto_plugin.so to ar.
