dev-lang/ghc: Filter LTO flags

LTO does not seem to be supported upstream. Add 'filter-lto' and 'append-flags -fno-strict-aliasing' to src_configure. See: http://brandon.si/code/initial-hacking-of-ghc-for-gcc-link-time-optimization/ Closes: https://bugs.gentoo.org/855596 Signed-off-by: hololeap <[email protected]> Signed-off-by: Sam James <[email protected]>
