[gentoo-dev] [PATCH] eclass/ruby-fakegem.eclass: guard against broken rdoc

[Hans de Graaff]

Skip building documentation rather than generating an error when rdoc is
missing but documentation is requested. rdoc should not be missing
normally, but this is a common problem when updating from one ruby
target straight to another one. There can be a gap when eselect has not
been triggered again yet for rdoc and another core ruby package may
require rdoc. This is commonly bundler since it has a +doc USE flag.
