Don't know how to fix it. For the records, in the emacs-26 branch,
tramp.elc contains

--8<---------------cut here---------------start------------->8---
(defalias 'tramp-lookup-syntax #[257 "\301 \236A\206\f\302\303\"\207" [tramp-syntax #[0 "\301\267\202\n\302\207\303\207\207" [tramp-syntax #s(hash-table size 2 test eq rehash-size 1.5 rehash-threshold 0.8125 purecopy t data (ftp 6 sep 8)) default separate] 2 ("/usr/local/src/emacs-26/lisp/net/tramp-compat.elc" . 7408)] error "Wrong `tramp-syntax' %s"] 4 (#$ . 25891)])
--8<---------------cut here---------------end--------------->8---

OTOH, in the Tramp git repository, branch tramp-2-3-stable, tramp.elc contains

--8<---------------cut here---------------start------------->8---
(defalias 'tramp-lookup-syntax #[257 "\301\267\202\302\202\303\202\236A\206\304\305\"\207" [tramp-syntax #s(hash-table size 2 test eq rehash-size 1.5 rehash-threshold 0.8125 purecopy t data (ftp 6 sep 10)) default separate error "Wrong `tramp-syntax' %s"] 4 (#$ . 25800)])
--8<---------------cut here---------------end--------------->8---

I have no idea where the absolute file name in the former comes
from. Both repositories use the same Emacs 26.1.91 binary for the build.

Best regards, Michael.
