build/x86: suppress GNU ld 2.39 warning about RWX load segments

Commit 68f5aac012b9 ("build: suppress future GNU ld warning about RWX
load segments") didn't quite cover all the cases: Apparently I missed
ones in the building of 32-bit helper objects because of only looking at
incremental builds (where those wouldn't normally be re-built). Clone
the workaround there to the specific Makefile in question.
