Rather than open a second bug for this part of the problem, let's leave this
PR to handle it; the first part of the problem that HJ originally reported can
be considered a part of bug 42690, which I'm in the course of testing the
attached patch as part of.
So, de-assigning myself from this PR. Possibly we should consider this a
build system bug and the makefile should be responsible for swapping sets of
gcda files in and out? Otherwise the component should be changed to lto.
