+    elf: Turn _dl_printf, _dl_error_printf, _dl_fatal_printf into functions
+    
+    This change makes it easier to set a breakpoint on these calls.
+    
+    This also addresses the issue that including <ldsodefs.h> without
+    <unistd.h> does not result usable _dl_*printf macros because of the
+    use of the STD*_FILENO macros there.
+    
+    (The private symbol for _dl_fatal_printf will go away again
+    once the exception handling implementation is unified between
+    libc and ld.so.)
