[PATCH] testsuite: Don't set SYMBOL_PREFIX for x86_64-*-cygwin

[Jon TURNEY <jon.turney@dronecode.org.uk>]

Exactly like x86_64-*-mingw, SYMBOL_PREFIX should not be set to "_" for
x86_64-*-cygwin

I'm not sure that testsuite results on x86_64-*-cygwin tell you a great deal,
but for the record:

-# of expected passes           20510
-# of unexpected failures       649
+# of expected passes           21456
+# of unexpected failures       729
 # of unexpected successes      2
 # of expected failures         42
-# of known failures            50
-# of untested testcases                90
-# of unresolved testcases      9
-# of unsupported tests         114
+# of known failures            52
+# of untested testcases                80
+# of unresolved testcases      184
+# of unsupported tests         118
