+MIPS: Avoid a dangling address@hidden' reference
+
+This satisfies a symbol reference created with:
+
+ .symver __libc_vfork, address@hidden
+
+where `__libc_vfork' has not been defined or referenced. In this case
+the address@hidden' reference is supposed to be discarded, however a
+bug present in GAS since forever causes an undefined symbol table entry
+to be created. This in turn triggers a problem in the linker that can
+manifest itself by link errors such as:
+
+ld: libpthread.so: invalid string offset 2765592330 >= 5154 for section
`.dynstr'
+
+The GAS and linker bugs need to be resolved, but we can avoid them too
+by providing a `__libc_vfork' definition just like our other platforms.
+
+ [BZ #17485]
+ * sysdeps/unix/sysv/linux/mips/vfork.S (__libc_vfork): Define.
