Patch to check if -fno-lifetime-dso is supported, before adding to cxxflags

The cause of this bug is a flag added in the ebuild:
        append-cxxflags -fno-lifetime-dse.
This flag was added because of bug #592590.
To fix this change the line to:
        append-cxxflags $(test-flags-CXX -fno-lifetime-dse).
Attached patch fixes the ebuild.

Without wanting to spam, this error also arose for me with an older in-tree version of gcc. I have not tested the patch.

Workround for gcc users:  use gcc-config to move to latest gcc (if possible!).
