The -Wtrampolines is that warning.  Note that -Wl,-z,noexecstack is a user
error in that case, you are requesting the linker to override any automatic
deduction on whether trampolines are used or not, by promising they aren't
used, even when you actually use them.  If you don't use -Wl,-z,noexecstack,
the compiler/assembler/linker will DTRT automatically, unless you have *.s/*.S
sources (those need to be tagged manually, or with -Wa,--noexecstack).
