rs6000: Fix gcc.target/powerpc/ti_math1.c on GCC 5 (PR69019)
This testcase currently fails on GCC 5, for LE only. Since it is fixed
for 6 and later, and backporting the relevant code is rather invasive,
let's just weaken the testcase for GCC 5 instead.

gfc_current_locus from old_locus even if there is no label.
