haskell-cabal.eclass: filter out -flto|-flto=* flags
`ghc` uses partial linking to glue together object
files produced by `gcc` and `ghc`. In case of -flto*
flags we have a chance to mix IR section incorrectly
due to ld deficiency: https://sourceware.org/PR12291
Let's filter out -flto-related flags until binutils is
ready.

Closes: https://github.com/gentoo-haskell/gentoo-haskell/issues/1110
