The gtt-doc.make is not required for "make dist" now. So
gtk-doc is completely optional now.
Let's keep gtk-doc disabled by default.
This reverts commit 57facddbc5.
This patch add "check|yes|no" concept for --{disable,enable}-gtk-doc
configure option. (We use the same concept for many u-l-ng compile
options.)
The gtk-doc is required for "make dist" (not sure if this is good
idea..), so it makes sense to enable gtk-doc by default.

Currently gtk-doc is optional. Unfortunately, the ./configure script
still depends on GTK_DOC_CHECK macro and shlibs/blkid/docs/Makefile.am
depends on gtk-doc.make.
It seems that the best solution is to add gtk-doc.[make,m4] files to
the repository.
