+Since no one has volunteered to test and fix these configurations,

+
+Valid cases of @samp{i@var{x}86} include @samp{i386}, @samp{i486},
+@samp{i586}, and @samp{i686}. All of those configurations produce a
+library that can run on this processor and newer processors. The GCC
+compiler by default generates code that's optimized for the machine it's
+configured for and will use the instructions available on that machine.
+For example if your GCC is configured for @samp{i686}, gcc will optimize
+for @samp{i686} and might issue some @samp{i686} specific instructions.
+To generate code for other models, you have to configure for that model
+and give GCC the appropriate @samp{-march=} and @samp{-mcpu=} compiler
+switches via @var{CFLAGS}.
