Hello!

zsh from master fails to build man pages

$ make
> . . .
> make[2]: Leaving directory `/home/rdautkha/zsh/zsh/Src'
> make[1]: Leaving directory `/home/rdautkha/zsh/zsh/Src'
> make[1]: Entering directory `/home/rdautkha/zsh/zsh/Doc'

> helpfiles: man and nroff -man both failed for zshbuiltins.1

All of the produced .1 files are of zero length

RHEL 7.6
autoconf 2.69
gcc 4.8.5
make.x86_64                        1:3.82-23.el7
Let me know if there is a way to fix this?


Thank you,
