skips all the further tests in that function if
check_effective_target_tls_runtime returns true. (I'm not sure why it
does that on C6X - it seems to link in emutls stuff?) We then fail with
unresolved __gcov symbols.
Fixed with the following patch. I've removed the new avr special case,
assuming it was intended to fix the same issue. Ok?

Don't rely solely on TLS tests for -fprofile-generate, fall
through to the other code.
