lto/114655 - -flto=4 at link time doesn't override -flto=auto at compile
time

The following adjusts -flto option processing in lto-wrapper to have
link-time -flto override any compile time setting.

PR lto/114655
* lto-wrapper.cc (merge_flto_options): Add force argument.
(merge_and_complain): Do not force here.
(run_gcc): But here to make the link-time -flto option override
any compile-time one.
