JDK-8334217 : [AIX] Misleading error messages after JDK-8320005

[suchismith1993]

dll_load_library() call fails is not analyzed (the ebuf content is ignored) dll_load_library does not analyze the contents of ebuf which leads to misleading error message when library loading fails.

We now call the second dll_load_library() only if the first returns with a 'No such file or directory' error message. If the first dll_load_library() found the library is not able to load it by any reason, we do not try again with a .a extension. JDK-8334217
