libjsig debug info has issues on MacOS X

While helping Ron Durbin analyze the following bug:

    JDK-8038132 jprt bundles have libjsig.dylib in different place on OSX

we observed a problem with the JPRT generated bits for MacOS X. I'm filing
the bug for Ron because he's about to leave on vacation.

Here is a very recent JPRT job:

$ pwd
/net/prt-archiver/data/jprt/archive/2014/05/2014-05-30-204710.amurillo.jdk9-hs-2014-05-30-snapshot/bundles

And here are the MacOS X product bits for that JPRT job:

$ unzip -l macosx_x64_10.7-product.zip | grep libjsig.
      2333 05-30-2014 13:56 jre/lib/libjsig.diz
    15112 05-30-2014 13:56 jre/lib/libjsig.dylib
        0 05-30-2014 09:03 jre/lib/libjsig.dylib.dSYM/
        0 05-30-2014 09:03 jre/lib/libjsig.dylib.dSYM/Contents/
      642 05-29-2014 09:16 jre/lib/libjsig.dylib.dSYM/Contents/Info.plist
        0 05-30-2014 09:03 jre/lib/libjsig.dylib.dSYM/Contents/Resources/
        0 05-30-2014 09:03 jre/lib/libjsig.dylib.dSYM/Contents/Resources/DWARF/
     8346 05-29-2014 09:16 jre/lib/libjsig.dylib.dSYM/Contents/Resources/DWARF/libjsig.dylib
       21 05-30-2014 09:03 jre/lib/server/libjsig.dylib.dSYM

The debug info file shown above:

     8346 05-29-2014 09:16 jre/lib/libjsig.dylib.dSYM/Contents/Resources/DWARF/libjsig.dylib

is stale. It is not the debug info that was generated by Alejandro's JPRT job.
Erik dealt with a similar issue for libjvm using the following bug:

    JDK-8033580 Old debug information in IMPORT_JDK is not removed

The astute observer might notice that the jre/lib/server/libjsig.dylib symlink is
missing from the above listing. That problem is being handled with Ron's fix:

    JDK-8038132 jprt bundles have libjsig.dylib in different place on OSX


Here are the MacOS X fastdebug bits for Alejandro's job:

Update: in the original version of this note, I had the libjvm info here instead
of the libjsig info. Too used to dealing with libjvm I guess...

$ unzip -l macosx_x64_10.7-fastdebug.zip | grep libjsig
     2333 05-30-2014 13:57 jre/lib/libjsig.diz
    15112 05-30-2014 13:57 jre/lib/libjsig.dylib

The JPRT fastdebug bits don't have the problem with stale debug info files.
