Specify a line number in the second dg-error to tell dejagnu what line to 
expect the error on.

{ dg-error "expected regexp" "test name" { target *-*-* } line-number }
or
{ dg-error "expected regexp" "test name" { xfail *-*-* } line-number }

It ought to be in the dejagnu manual (i.e., that's where documentation 
should best be contributed) since dg-error is part of base dejagnu.
