similar patch is used by the Yocto Project, and they have already
submitted it upstream.

+Subject: [PATCH] Remove incorrect dependency from install-data-hook
+
+Having install-binPROGRAMS as a dependency of install-data-hook is not
+correct, as it causes the installation of programs to be executed
+twice, and those two installations are racing with each other, causing
+random installation failures.
+
+In addition, this dependency is not needed: the install-data-hook
+calls the update-mime-database program in one of two ways:
+
+ - When cross-compiling, using the program pointed by
+   UPDATE_MIME_DATABASE, which is already built, and is not installed
+   by install-binPROGRAMS.
+
+ - When compiling natively, suing the update-mime-database from the
+   build directory, so there is no need to depend on
+   install-binPROGRAMS.
+
+This patch is similar to the patch used by the Yocto Project at
+http://git.yoctoproject.org/cgit.cgi/poky/plain/meta/recipes-support/shared-mime-info/shared-mime-info/install-data-hook.patch.
