+Subject: [PATCH] Delay adding sysroot path to module name in case of non
+ absolute executable
+
+Current stap code adds sysroot prematurely for probes that specify non
+absolute path name, i.e like "foo", so when find_executable called it
+receives full path as <sysroot>/foo and find_executable does not search
+PATH while applying sysroot.
+
+Fix delays adding sysroot till path inside of sysroot is searched first.
+
+Also fix missing sysroot addition in glob expansion case.
+
