See the flex-boot0 package in 'gnu/packages/commencement.scm. This
package inherits from flex but limits the native-inputs to bison-boot0
and %boot0-inputs. So, lzip is not available here.

Although I didn't try building it from the lzip-compressed tarball, I
expect flex-boot0 would fail to build unless we added lzip to its
native-inputs. Did work for you?

Right, since commit 93fabf59962aeb15981bd547850de1dab69eccfb (gnu: flex:
Update to 2.6.4.) the flex package was broken. We didn't notice right
away because it was on core-updates.
