+Subject: [PATCH] debuginfo lookup with sysroot case do not remove sysroot from
+ file_name
+
+If sysroot option is passed, and debug symbols reside in sysroot along
+with executable <foo> in <foo_dir>/.debug/<foo_file> directory,
+stap fails to find debuginfo because it strips out sysroot path
+from file_name so dwfl_standard_find_debuginfo ends up looking at
+host <foo_dir>/.debug/<foo_file> rather then checking
+<sysroot>/<foo_dir>/.debug/<foo_file>.
