Make Memcheck work sanely on AIX5.3 (again):

* Don't intercept putenv/getenv/setenv.  Causes a lot of whinging
  about missing TOC pointers.

* Add 'strcmp' to the bundle of 4 functions intercepted in all
  objects.

* xlc now seems to route calls through to malloc_common, free_common,
  calloc_common, realloc_common, memalign_common in libc.  Intercept
  those names too.
