The -P option is provided for Solaris compatibility.
+@kindex --enable-linker-version
+@item --enable-linker-version
+Enables the @code{LINKER_VERSION} linker script directive, described
+in @ref{Output Section Data}. If this directive is used in a linker
+script and this option has been enabled then a string containing the
+linker version will be inserted at the current point.
+
+Note - this location of this option on the linker command line is
+significant. It will only affect linker scripts that come after it on
+the command line, or which are built into the linker.
+
+@kindex --disable-linker-version
+@item --disable-linker-version
+Disables the @code{LINKER_VERSION} linker script directive, so that it
+does not insert a version string. This is the default.

+@kindex LINKER_VERSION
