[PATCH] build/non-x86: fix symbol lookup in presence of build-id

[Jan Beulich <jbeulich@xxxxxxxx>]

It's not clear why only x86 had $(build_id_linker) applied to all three
linking passes. Not doing so will alter symbol offsets between the 2nd
and 3rd passes for, potentially, all of the symbols at higher addresses
(intermediate alignment padding may mask this effect, though, so it will
look as if problems appeared randomly).

Fixes: a353cab905af ("build_id: Provide ld-embedded build-ids")
