8  * These two symbols are declared in a C file so that the linker
9  * uses R_ARM_RELATIVE relocation, rather than the R_ARM_ABS32 one
10  * it would use if the symbols were defined in the linker file.
11  * Using only R_ARM_RELATIVE relocation ensures that references to
12  * the symbols are correct after as well as before relocation.
13  *
14  * We need a 0-byte-size type for these symbols, and the compiler
15  * does not allow defining objects of C type 'void'. Using an empty
16  * struct is allowed by the compiler, but causes gcc versions 4.4 and
17  * below to complain about aliasing. Therefore we use the next best
18  * thing: zero-sized arrays, which are both 0-byte-size and exempt from
19  * aliasing warnings.
