Right, I noticed this myself.  Most likely just another one of the many
instances of mindless copy-and-paste programming in our testsuite ;-(

I've now applied the following patch to fix this, after testing on
x86_64-unknown-linux-gnu.

Btw., I've started implementing a dwarf2_debug_line effective-target
keyword for the testsuite.
