+Tells GCC to consider @var{dir} as the system root (see
+@option{--with-sysroot}) while building the compiler itself, instead of
+the directory specified with @option{--with-sysroot}. This option is
+only useful when you are already using @option{--with-sysroot}. You

+@option{--prefix} set to a directory that is different from the one in

Deprecated in favor of @option{--with-sysroot}.
