Hi!

Like with gcc-6 in #885428, we need to patch src:gcc-7 to use the
internal libunwind library when cross-building for a ia64 target.

The attached patch makes the necessary modifications which have
been verified to work in rebootstrap. A second patch by James
Clarke is necessary to modify some linker flags for building
the internal libunwind. I will file a second bug report for that.
