libquadmath lacks this definition, and apparently as a result running
'make install infodir=/some/where' installs some multilib copies of
libquadmath.info in directories based on $prefix rather than the
infodir passed at install time. This patch fixes this problem.
Bootstrapped with no regressions on x86_64-unknown-linux-gnu. OK to
commit?
(I do not know whether bugs may arise in other target libraries from
their lack of this definition; it's specifically libquadmath where
I've observed the problem as a regression in 4.6/4.7 with an info file
newly installed in the wrong place.)
