+Generate code that allows (does not allow) a static executable to be
+relocated to a different address at runtime. A simple embedded
+PowerPC system loader should relocate the entire contents of
+@code{.got2} and 4-byte locations listed in the @code{.fixup} section,
+a table of 32-bit addresses generated by this option. For this to
+work, all objects linked together must be compiled with
+@option{-mrelocatable} or @option{-mrelocatable-lib}.
+@option{-mrelocatable} code aligns the stack to an 8 byte boundary.

+Like @option{-mrelocatable}, @option{-mrelocatable-lib} generates a
