qemu: fix recent reproducibility issues

Not only break when not in a loop is undefined, different
shells do different things when they see it.

+Subject: [PATCH] configure: Fix check-tcg not executing any tests
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+After configuring with --target-list=hexagon-linux-user
+running `make check-tcg` just prints the following:
+
+```
+make: Nothing to be done for 'check-tcg'
+```
+
+In the probe_target_compiler function, the 'break'
+command is used incorrectly. There are no lexically
+enclosing loops associated with that break command which
+is an unspecfied behaviour in the POSIX standard.
+
+The dash shell implementation aborts the currently executing
+loop, in this case, causing the rest of the logic for the loop
+in line 2490 to be skipped, which means no Makefiles are
+generated for the tcg target tests.
+
+Fixes: c3b570b5a9a24d25 (configure: don't enable
+cross compilers unless in target_list)
