+It is easy to configure the GNU C library for cross-compilation by
+setting a few variables in @file{configparms}.  Set @code{CC} to the
+cross-compiler for the target you configured the library for; it is
+important to use this same @code{CC} value when running
+@code{configure}, like this: @samp{CC=@var{target}-gcc configure
+@var{target}}.  Set @code{BUILD_CC} to the compiler to use for for
+programs run on the build system as part of compiling the library.  You
+may need to set @code{AR} and @code{RANLIB} to cross-compiling versions
+of @code{ar} and @code{ranlib} if the native tools are not configured to
+work with object files for the target you configured for.

 Some of the machine-dependent code for some machines uses extensions in
 the GNU C compiler, so you may need to compile the library with GCC.
 (In fact, all of the existing complete ports require GCC.)
