Build failed OpenSC-0.17.0-rc2

[hamano]

Expected behaviour

configure must fail if help2man doesn't installed and generate npa-tool.1 at build time.
I propose to include the npa-tool.1 in the source archive.

Actual behaviour

Passed configure and failed at make.

Steps to reproduce

$ cat /etc/debian_version
9.0
$ dpkg -l help2man
dpkg-query: no packages found matching help2man
$ wget https://github.com/OpenSC/OpenSC/releases/download/0.17.0-rc2/opensc-0.17.0.tar.gz
$ tar xf opensc-0.17.0.tar.gz
$ cd opensc-0.17.0
$ ./configure

$ make
