You'll generally need something like 512Mb of available memory, i.e. RAM 
+ swap, with the linker in particular benefiting from extra. Around 
here, I'm being firmly discouraged (by other colleagues with an 
electronics background) from putting swap on the card, but instead 
putting it on an external USB device with wear levelling.
