[PATCH 5.17 618/772] objtool: Fix objtool regression on x32 systems

[Greg Kroah-Hartman]

From: Mikulas Patocka <mpatocka@xxxxxxxxxx>

commit 22682a07acc308ef78681572e19502ce8893c4d4 upstream.

Commit c087c6e7b551 ("objtool: Fix type of reloc::addend") failed to
appreciate cross building from ILP32 hosts, where 'int' == 'long' and
the issue persists.

As such, use s64/int64_t/Elf64_Sxword for this field and suffer the
pain that is ISO C99 printf formats for it.

Fixes: c087c6e7b551 ("objtool: Fix type of reloc::addend")
