That is an interesting and surprisingly difficult to debug error you
have there.  On Guix System, we have
--8<---------------cut here---------------start------------->8---
$ ldd $GUIX_ENVIRONMENT/bin/.emacs-27.2-real | grep lzma
	liblzma.so.5 => /gnu/store/c8isj4jq6knv0icfgr43di6q3nvdzkx7-xz-5.2.5/lib/liblzma.so.5 (0x00007f7919fee000)
--8<---------------cut here---------------end--------------->8---
where xz is one of those magic libraries you'd expect to exist in any
distro.  However,

--8<---------------cut here---------------start------------->8---
$ guix show emacs | recsel -p dependencies

If at all, xz is included as implicit input to unpack Emacs!  We should
probably add it as explicit input instead.

Cheers
