Fix stdlib/tst-setcontext.c for GCC 12 -Warray-compare
Building stdlib/tst-setcontext.c fails with GCC mainline:
tst-setcontext.c: In function 'f2':
tst-setcontext.c:61:16: error: comparison between two arrays [-Werror=array-compare]
61 | if (on_stack < st2 || on_stack >= st2 + sizeof (st2))
| ^
tst-setcontext.c:61:16: note: use '&on_stack[0] < &st2[0]' to compare the addresses
The comparison in this case is deliberate, so adjust it as suggested
in that note.
Tested with build-many-glibcs.py (GCC mainline) for aarch64-linux-gnu.
