#7456: GHC API displays linker messages to stdout instead of via log_action

----------------------------+-----------------------------------------------
At least in the LinkInMemory mode, GHC API displays linker messages, such
as
{{{
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
}}}
on stdout instead of using the log_action handler for them, just as for
all the other kinds of messages. Moreover, I haven't found any way of
suppressing these messages apart of setting verbosity=0, which turns off
other important messages. I can see no GHC flags that does this and this
linker does not accept any special linker flags. I don't know the policy
about severity levels, but I suppose severity SevOutput could be fine for
these messages, by similarity to "compiling M ... done." messages which
have such severity.
