This is a mere implementation detail.  You could use a pointer
instead, which would then point to the RO data segment.  You could
even use some  __attribute__ ((section(".text")))  to make sure the
"instruction" is really in the text segment, for example (untested):

	const uint32_t insn __attribute__ ((section(".text"))) = 0xe25ef004;
	vt[4] = &insn;
