Patch: RFA: Set default value for java.library.path

[Thomas Fitzsimmons]

Hi,

java.library.path should default to the contents of the shared library
path environment variable (LD_LIBRARY_PATH on GNU/Linux).  To make this
cross-platform I've used libltdl's AC_LTDL_SHLIBPATH macro to define
LTDL_SHLIBPATH_VAR.  With this patch the aclocal call used in
gcc/libjava needs one extra -I argument, becoming:

aclocal -I . -I .. -I ../config -I ./libltdl

The order of -I arguments to aclocal is important; misplacing
-I ./libltdl gives strange results.

OK for mainline?

Tom

	PR libgcj/23762
	* configure.ac: If libltdl is being used call AC_LTDL_SHLIBPATH
	macro.
	* gnu/classpath/natSystemProperties.cc (insertSystemProperties)
	[USE_LTDL]: If it was not defined with -D set java.library.path to
	the value of LTDL_SHLIBPATH_VAR.
