There is no justification for changing some shared library file names
depending on the platform used.

We want to be buildable on Mac OS X without pkg-config. For instance
Mono installs a symlink /usr/bin/pkg-config that just confuses this
goal if you happen to build LibreOffice on a machine with Mono
installed.

These ones were never present in the recorded history of the project
to begin with.

use $HOME/.config unless XDG_CONFIG_HOME is set with respect to
http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html
moreover, lose dot so as "$HOME/.config/libreoffice".

Conflicts:
	configure.in
	distro-configs/LibreOfficeMacOSX.conf
	distro-configs/OxygenOfficeLinux.conf
	distro-configs/OxygenOfficeWin32.conf
	download
	instsetoo_native/util/openoffice.lst
	ooo.lst.in
	set_soenv.in
	solenv/bin/modules/installer/download.pm
	solenv/gbuild/CppunitTest.mk
	solenv/inc/minor.mk
	solenv/inc/settings.mk

allow to generate the log into another directory

Also, add instsetoo_native to the ignore list.

Just list the OSes for which there is no "system" installed GLib etc
in one case in the case statement. Add iOS to the set.
