We probably want the title of the patch to be:

	eigen: add an option to install unsupported modules

Indentation is wrong here: there should be one tab before the "bool"
statement.

I'm a bit worried about having a directory called
$(STAGING_DIR)/usr/include/unsupported. Shouldn't this directory be
installed *below* the $(STAGING_DIR)/usr/include/Eigen directory
created by the normal installation of Eigen?

I believe we normally don't really use post install hooks when there is
a definition of the staging install commands. Instead, we use the
following idiom:

ifeq ($(BR2_PACKAGE_EIGEN_UNSUPPORTED_MODULES),y)
define EIGEN_INSTALL_UNSUPPORTED_MODULES_CMDS
	cp -a ...
endef
endif

define EIGEN_INSTALL_STAGING_CMDS
	... existing installation steps ...
	$(EIGEN_INSTALL_UNSUPPORTED_MODULES_CMDS)
endef
