+Renames "libtool" -> "${TARGET_PREFIX}libtool" which makes sure

+
+It also adjusts libtool so that the header at the script is used for 
+script execution and not thevalue of $SHELL. This is because many 
+Makefiles change $SHELL so dash can get used to execute what is 
+otherwise configured as a bash shell script. Since we don't need to 
+execute scipts this way on any system I'm aware of us building upon, 
+the simplest fix is just to remove $SHELL.

+Upstream-Status: Pending
+
+When using sysroot we should append it to libdir, which is helpful in
+cross builds as the system is staged in the sysroot. For normal builds,
+i.e. when lt_sysroot is not set, it will still behave the same and add
+-L/usr/lib to the relink command.
