Linker fails to link example like this (simplified case from newlib
sources):
$ cat test.c
extern const char _ctype_b[];
struct _t { char *ptr; };
struct _t T = { ((char *) _ctype_b + 3) };
$ cat ctype.c
char _ctype_b[4] = { 0, 0, 0, 0 };
LD: test.o:(.data+0x0): warning: internal error: unsupported relocation error
We also follow gnu toolchain here, where 2-byte relocation mapped to
R_MSP430_16_BYTE, instead of R_MSP430_16.
