 You are the author of this code, so I guess you know what's going on 
here.  I still don't understand the circumstances that cause linker.c to 
reject this symbol if it's in an SHN_MIPS_SCOMMON rather than SHN_COMMON 
section, and the relevant git change descriptions (going back to commit 
b794fc1d1c3a ("Warn for ar/nm/ranlib/ld on lto objects without plugin")) 
do not explain it, so I'd appreciate if you got me enlightened.
