The main change (support for .ARM.exidx unwind info) is already in Ubuntu GDB (came in with the Linaro GDB merge).
There is one minor additional fix (actually a pre-existing bug in the ARM prologue parser exposed by the glibc change) that is not yet in Ubuntu GDB. This extra fix has been committed to mainline GDB: http://sourceware.org/ml/gdb-patches/2011-03/msg00964.html
and also to Linaro GDB (rev. 32997).
