jextract symbolic link handling

[Andre Blanke]

Hi,

it appears jextract is not able to handle -l arguments which are symbolic
links pointing to the actual library, which is the case for some libraries
on my system.

Would it be possible to implement support for this?

It should be a fairly simple fix by replacing the Path::toAbsolutePath
method reference inside of com.sun.tools.jextract.Utils.findLibraryPath
with a call to Path.toRealPath and adding code for handling a potential
IOException.

Thanks,
Andre
