Indeed, thanks for pointing out.

I tried and it failed with

	starting phase `configure'
	source directory: "/tmp/guix-build-emacs-dev-26.0.91.drv-0/source" (relative from build: ".")
	build directory: "/tmp/guix-build-emacs-dev-26.0.91.drv-0/source"
	configure flags: ("CONFIG_SHELL=/gnu/store/icz3hd36aqpjz5slyp4hhr8wsfbgiml1-bash-minimal-4.4.12/bin/bash" "SHELL=/gnu/store/icz3hd36aqpjz5slyp4hhr8wsfbgiml1-bash-minimal-4.4.12/bin/bash" "--prefix=/gnu/store/iaipasvi8dys79ms3y0axvwwdfnd31dq-emacs-dev-26.0.91" "--enable-fast-install" "--build=x86_64-unknown-linux-gnu")
	configure: WARNING: unrecognized options: --enable-fast-install
	./configure: line 3350: config.log: Permission denied
	./configure: line 3360: config.log: Permission denied
	phase `configure' failed after 0.1 seconds

I inspected the content of
"/tmp/guix-build-emacs-dev-26.0.91.drv-0/source": many files are
missing, among others "configure".

I am very confused...
