You are absolutely right - this code is not valid from the point of view of
formal standard C language. It is illegal to provide multiple definitions of
external objects with the same name.
However, this is a popular extension in C implementations with Unix heritage.
So, this entry is about the intended non-standard behavior of GCC
compiler/linker.
