-Watch the commands executed during the build. On the Linux machines,
-the ordinary system tools are used. On a SPARC machine, special build
-tools are used, whose names begin with @samp{i386-elf-}, e.g.@:
-@code{i386-elf-gcc}, @code{i386-elf-ld}. These are ``cross-compiler''
-tools. That is, the build is running on a SPARC machine (called the
-@dfn{host}), but the result will run on a simulated 80@var{x}86 machine
-(called the @dfn{target}). The @samp{i386-elf-@var{program}} tools are
-specially built for this configuration.
