Support the use of `make install` in packaging scripts, where the $mandir tree might not exist under $DESTDIR. For portability, create the parent directories using a separate install command instead of relying on the non-portable `-D` flag. Set errexit so the install target fails if any install step fails.

Docker Engine Documentation
The man pages for Docker Engine are generated from the markdown sources and tooling in this directory.
Generate the man pages
Run make from within this directory.
A Go toolchain is required.
The generated man pages will be placed in manN subdirectories, where N is the manual section number.
Install the man pages
Run make install from within this directory.
The make variables prefix, mandir, INSTALL, INSTALL_DATA and DESTDIR
are supported for customizing the installation.
Add a new man page
Create a new Markdown file in this directory with a filename TITLE.SECTION.md, where TITLE is the man page title and SECTION is the section number. The Makefile will pick it up automatically.
The Makefile ignores Markdown files that do not match the glob *.*.md,
allowing non-manpage documentation (like this README file) to coexist.
