​Ugh. This might be tricky.  Your 19c linux binary supports the
:linkage-table *feature*. But alpha doesn't. I'm not sure how well
cross-compiling from linux to alpha will work in this case. And I don't
remember what a cross-compile without :linkage-tables looks like anymore,
and all of the current working ports use :linkage-tables.

So, these undefined symbols might be ok, but they do have to get resolved
in some way.  call_into_c ought to exist in your lisp.nm file. Perhaps
genesis is not parsing that file correctly?​

​(See load-foreign-symbol-table in compiler/new-genesis.lisp.)
