In principle, there are no such dependencies.

However, you have to keep in mind that a 32 bits tool chain cannot
build 64 bits binaries.  In case you installed the ELDK from the
binaries on our FTP server, you should be aware that these are 32 bit
binaries (for wider compatibility to existing host environments).
You will need to rebuild the ELDK for a x86_64 host; make sure to set

	SDKMACHINE = "x86_64"

in your conf/local.conf file - in the binary distribution we build
with SDKMACHINE ?= "i686".
