With --trace-imports the entry stub resolves TraceImport_nid_no_patch
in libc.prx and passes each function import through it before writing
the slot: every PLT slot, and a GOT slot only when the original symbol
is a function, so data imports such as __stdoutp keep their address.
Without the option the output is unchanged.

Weak undefined imports in the input ELF became STB_GLOBAL in the relinked
output, so a title that weak-imports a function no module exports stopped
at startup instead of binding the import to null.
Keep STB_WEAK on the relinked dynamic symbols. On Windows, write 0 plus
the addend to the slot of a weak import that no searched module exports.

A relocation whose dynamic symbol entry is all zero, like the null symbol,
now takes the value 0 plus its addend, as the gABI defines for STN_UNDEF.
The Linux output imports such an entry as an unnamed weak symbol, which the
host loader resolves to 0. The Windows and macOS outputs write the value
into the slot instead of failing with "Empty import symbol name". Such
references are left out of the call registry. An unnamed symbol entry that
is not all zero still fails the relink.
OliSe Player (PPSA01153) has seven of these entries and calls through the
slots only when they are not 0 (#4437).
