lib.o:(*IND*+0x0): multiple definition of `efi_set_variable' about efivar

[superm1]

So the most obvious solution is:

Index: efivar-30/Make.rules
===================================================================
--- efivar-30.orig/Make.rules
+++ efivar-30/Make.rules
@@ -18,6 +18,7 @@ include $(TOPDIR)/Make.version

 %.so :
    $(CCLD) $(ccldflags) $(CPPFLAGS) $(SOFLAGS) \
+     -Wl,-z,muldefs \
      -Wl,-soname,[email protected] \
      -Wl,--version-script=$(MAP) \
      -o $@ $^ $(LDLIBS)

I only see the one definition in lib.c and the version script only refers in one version, so adding that is probably masking something else odd.

So whether that's the right solution I guess is up to @vathpela

Huh, that might actually work. FWIW this appears to be a compiler bug (the multiple definitions are symbol versioning, which should just work), and it goes away with -flto.

But I'm totally okay working around it with -z muldefs. I'd rather put it in ccldflags, though.
