[PATCH] tile: exit with status zero on makecontext return with NULL uc_link

- Subject: [PATCH] tile: exit with status zero on makecontext return with NULL uc_link
---
Tile was correctly calling exit() on a NULL uc_link, but not actually
setting the exit code to any particular value. We want exit(0), so
change the assembly to make it happen that way.
