(or set of directories, as in LD_LIBRARY_PATH) to search for all
shared libraries if not found in SOLIB_ABSOLUTE_PREFIX.
Search order:
* If path is absolute, look in SOLIB_ABSOLUTE_PREFIX.
* If path is absolute or relative, look for it literally (unmodified).
Search algorithm:
* If there is a solib_absolute_prefix and path is absolute:
* Search for solib_absolute_prefix/path.
* else
* Look for it literally (unmodified).
* Look in SOLIB_SEARCH_PATH.
* If available, use target defined search function.
* Look in inferior's $PATH.
* Look in inferior's $LD_LIBRARY_PATH.
* If solib_absolute_prefix is NOT set, perform the following two searches:
* Look in inferior's $PATH.
* Look in inferior's $LD_LIBRARY_PATH.
*
* The last check avoids doing this search when targetting remote
* machines since solib_absolute_prefix will almost always be set.
