gdb.base/break-interp.exp failure

[Ulrich Weigand]

This test fails due to missing symbols ld.so (because it is stripped). Need to fix the testcase.

Large numbers of failures were fixed by this mainline patch:
http://sourceware.org/ml/gdb-patches/2010-10/msg00177.html

I've checked in the following patch to fix several additional failures (timeouts):
http://sourceware.org/ml/gdb-patches/2010-10/msg00195.html

One remaining set of failures is due to unwinding problems out of glibc without debuginfo:

Checked in backports from mainline. This fixes the problem completely on x86. The remaining failures on arm will be fixed if unwind support for ARM exception tables is added, see LP #661253
