java.library.path fix for MacOS X (7145798)

[Daniel D. Daugherty]

Greetings,

Apple's version of Java includes "." in the java.library.path
at the beginning. OpenJDK includes "." at the end of
java.library.path on Windows. On Linux and Solaris, "." is
not included at all.

In the MacOS X port project, the relevant code was copied from
Linux so "." is not present in java.library.path. This should
be changed to make the OpenJDK7 version on MacOS X behave
similar to the Apple version of Java6.

Here is the webrev URL:

There more lines of comment in there than code...

Thanks, in advance, for any feedback.

Dan
