I suspected the --as-needed flag of being the culprit at first myself,
but it turned out not to be that simple—the switches that would add
the libs just refuse to appear in the ld command, even if --no-as-needed
is passed.  Adding the libs manually to the end of the line makes the
command go through, but that doesn't help with the ebuild.

Thanks for trying, though.
