     \begin{itemize}
     \item Kernel headers version
     \item C library: Buildroot supports uClibc, (e)glibc and musl
-    \item Version of binutils and gcc
+      \begin{itemize}
+      \item (e)glibc, the standard C library. Good choice if you don't
+        have tight space constraints ($>=$ 10 MB)
+      \item uClibc and musl, smaller C libraries. uClibc supports
+        non-MMU architectures. Good for very small systems ($<$ 10 MB).
+      \end{itemize}
+    \item Different versions of binutils and gcc. Keep the default
+      versions unless you have specific needs.
     \item Numerous toolchain options: C++, LTO, OpenMP, libmudflap,
       graphite, and more depending on the selected C library.
     \end{itemize}
-  \item Built using a number of normal Buildroot packages
   \item Building a toolchain takes quite some time: 15-20 minutes on
     moderately recent machines.
   \end{itemize}
