Problem with relative paths in update-gems makefile rule (common.mk)

Description

When I do

make update-gems
I get the following error:

-e:1:in `require': cannot load such file -- downloader (LoadError)
uncommon.mk:1084: recipe for target 'update-gems' failed
make: *** [update-gems] Error 1

The reason for this seems to be a problem with relative paths.
The rule for update-gems in common.mk is as follows:

update-gems: PHONY
	$(ECHO) Downloading bundled gem files...
	$(Q) $(RUNRUBY) -I$(srcdir)/tool -rdownloader -answ \
	    -C "$(srcdir)/gems" \
	    -e 'gem, ver = *$$F' \
	    -e 'gem = "#{gem}-#{ver}.gem"' \
	    -e 'Downloader::RubyGems.download(gem)' \
	    bundled_gems

$(srcdir) is just '.', and so './tool' gets added to the load path, but then -C "$(srcdir)/gems" changes to the gems subdirectory, from which './tool' doesn't point to the tool directory anymore.
