Remove dead code in config/rs6000/vxworks.h

[Eric Botcazou via Gcc-patches]

These lines were added last year:

/* Initialize library function table.  */
#undef TARGET_INIT_LIBFUNCS
#define TARGET_INIT_LIBFUNCS rs6000_vxworks_init_libfuncs

but TARGET_INIT_LIBFUNCS is #undef-ed in config/rs6000/rs6000.c and 
rs6000_vxworks_init_libfuncs is nowhere defined in any case.

Applied on mainline and 11 branch as obvious.

        * config/rs6000/vxworks.h (TARGET_INIT_LIBFUNCS): Delete.
