Icecat uses an unusual thing called a "computed origin", which means
that its source is itself built from other sources.  The only two places
in Guix where this is currently done is 'icecat' and 'linux-libre'.

See 'computed-origin-method' and 'icecat-source' in
gnu/packages/gnuzilla.scm, and 'computed-origin-method' and
'make-linux-libre-source' in gnu/packages/linux.scm.
