 This will configure and build all the libraries as well as the
 assembler, the binutils, and the linker.
 
+Note - if you have obtained the sources by checking out a copy from
+the git repository then you will have both the binutils and GDB
+sources in one place.  In this case you may wish to add an option to
+the configure command line to stop it from configuring GDB.  This will
+also stop the configure script from checking the libraries that are
+needed by GDB, but not by the binutils.
+
+	./configure --disable-gdb 
+
+Since the configure script can be quite verbose, you may also
+want to add the --quiet option to reduce the amount of output. ie:
+
+	./configure --quiet
+
 If you have GNU make, we recommend building in a different directory:
 
 	mkdir objdir
