Running make psdocs on a Ubuntu 16.04 system fails with

Documentation/DocBook/Makefile:142: recipe for target
'Documentation/DocBook/kernel-hacking.ps' failed
make[1]: *** [Documentation/DocBook/kernel-hacking.ps] Error 9
Makefile:1442: recipe for target 'psdocs' failed
make: *** [psdocs] Error 2

possibly due to

[15.0.21]
! Undefined control sequence.
\Hy@wrapper@babel ...set@display@protect \edef \x

! Argument of \HyWrap@hyper@anchorstart has an extra }.
<inserted text>
                \par

                    \endSeq{}\Node%
Runaway argument?

Though I wonder how many people still build the psdocs version...
