Subject: [PATCH] Make it possible to build Inkscape 0.47 on RHEL 5

This contains various quirks to build against slightly older libraries
and tools. Specifically:

* Automake prior to 1.10 generated incorrect rules to build assembly files
which resulted in object files being placed in wrong directories.

* Configure required giomm-2.4 pkg-config package, which is provided by
recent gtkmm, but not by older one, though giomm-2.4 itself is present

* Cairo prior to 1.5.1 did not define macros for PostScript language
levels.

* GTK prior to 2.12.0 did not provide
gtk_entry_completion_set_inline_selection () function

* GLib prior to version 2.15.1 did not provide mechanisms for parsing
URIs.
