When building for arm32 with GNU binutils 2.39, the linker outputs
warnings when linking Trusted Applications:
arm-unknown-linux-uclibcgnueabihf-ld.bfd: warning: utee_syscalls_a32.o: missing .note.GNU-stack section implies executable stack
arm-unknown-linux-uclibcgnueabihf-ld.bfd: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
We could silence the warning by adding the '--no-warn-execstack' option
to the TA link flags, like we did in the parent commit for the TEE core
and ldelf. Indeed, ldelf always allocates a non-executable piece of
memory for the TA to use as a stack.
However it seems preferable to comply with the common ELF practices in
this case. A better fix is therefore to add the missing .note.GNU-stack
sections in the assembler files.
