Two profile tests `FAIL` on 32-bit Linux/sparc64:
```
Profile-sparc :: ContinuousSyncMode/runtime-counter-relocation.c
Profile-sparc :: ContinuousSyncMode/set-file-object.c
```
while the same tests work just fine on 64-bit. It turns out the same failures occur on Solaris/sparcv9: the tests don't seem to be actually Linux-specific. In fact, on Solaris/amd64 they `PASS` for both `i386` and `x86_64`.
Here are the actual failues:
```
Profile-sparc :: ContinuousSyncMode/runtime-counter-relocation.c
compiler-rt/test/profile/ContinuousSyncMode/runtime-counter-relocation.c:14:23: error: CHECK-COUNTS-NEXT: expected string not found in input

^
<stdin>:4:13: note: scanning from here
Counters: 2
^
<stdin>:5:2: note: possible intended match here

output is

Maybe one of the developers (@ZequanWu, @DavidSpickett, @petrhosek, @vedantk) can shed some light on where to start looking? These are among the very few last failing tests on Linux/sparc64.
