sparc64: vdso: Link with -z noexecstack
The vDSO stack does not need to be executable. Prevent the linker from
creating executable. For more background see commit ffcf9c5700e4 ("x86:
link vdso and boot with -z noexecstack --no-warn-rwx-segments").
Also prevent the following warning from the linker:
sparc64-linux-ld: warning: arch/sparc/vdso/vdso-note.o: missing .note.GNU-stack section implies executable stack
sparc64-linux-ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
Fixes: 9a08862a5d2e ("vDSO for sparc")
