`make install` fails

[fxcoudert]

We are building mxml in Homebrew, using ./configure --enable-shared --disable-debug --disable-dependency-tracking --prefix=/opt/homebrew/Cellar/libmxml/4.0.0 --libdir=/opt/homebrew/Cellar/libmxml/4.0.0/lib && make install

This fails with:

Yes, I noticed this last night and pushed a fix ([master 8a5c9ee Fix missing docdir in Makefile.in.]) Will be doing a 4.0.1 release later today...
