commit a4f3bc23461e3f9f6053e827715984ba0d2e589a

s390: Use long branches across object boundaries (jgh instead of jh)
Depending on the layout chosen by the linker, the 16-bit displacement
of the jh instruction is insufficient to reach the target label.
Analysis of the linker failure was carried out by Nick Clifton.
