That's already in the testcase.

	/* Test local calls between pcrel and non-pcrel code.

The comment goes on to say

	   Despite the cpu=power10 option, the code generated here should just
	   be plain powerpc64, even the necessary linker stubs.  */

which was the justification for using "dg-do run" unqualified in the
current testcase.

There aren't any.  And other tests use multiple dg-do lines, eg.
gcc/testsuite/g++.dg/ext/altivec-3.C

/* { dg-do run { target { powerpc*-*-* && vmx_hw } } } */
/* { dg-do compile { target { powerpc*-*-* && { ! vmx_hw } } } } */

Committed 2ba0674c657, and apologies for missing the power10_ok first
time around on this test.
