[ubsan]: temporarily disable print_stack_trace.cc test
Some problems with ARM stack unwinding led to inaccurate stack traces being
printed, which caused this test to fail on
// RUN: %clangxx -fsanitize=undefined -O0 %s -o %t && UBSAN_OPTIONS=stack_trace_format=DEFAULT:fast_unwind_on_fatal=1 %run %t 2>&1 | FileCheck %s
// RUN: %clangxx -fsanitize=undefined -O0 %s -o %t && UBSAN_OPTIONS=stack_trace_format=DEFAULT:fast_unwind_on_fatal=0 %run %t 2>&1 | FileCheck %s
+// This test is temporarily disabled due to broken unwinding on ARM.
+// UNSUPPORTED: -linux-
+
// The test doesn't pass on Darwin in UBSan-TSan configuration, because TSan is
// using the slow unwinder which is not supported on Darwin. The test should
// be universal after landing of https://reviews.llvm.org/D32806.
