+ Avoid .symver on common symbols [BZ #21666]
+
+ The .symver directive on common symbol just creates a new common symbol,
+ not an alias and the newer assembler with the bug fix for
+
+ https://sourceware.org/bugzilla/show_bug.cgi?id=21661
+
+ will issue an error. Before the fix, we got
+
+ $ readelf -sW libc.so | grep "loc[12s]"
+ 5109: 00000000003a0608 8 OBJECT LOCAL DEFAULT 36 loc1
+ 5188: 00000000003a0610 8 OBJECT LOCAL DEFAULT 36 loc2
