Comment (by JDLH):

 The `-export-symbols` arg appears to come from `dont-use-version-
 script.patch`, which contains:

 I am guessing that the syntax here is for Meson. There is a
 [https://mesonbuild.com/Reference-manual_functions.html#shared_library
 Meson shared_library() function] which takes a parameter `link_args:
 list[str]`. It looks like a [https://mesonbuild.com/Syntax.html#arrays
 list in Meson] might be delimited by square brackets.

 Maybe a thing to try is `link_args: ['-export-symbols ', symbol_map],`. Or
 `'-exported_symbols_list '`? I don't know, I am grasping at straws. If I
 get around to trying it before someone else does, I will let you know how
 it worked for me.
