gdb, gdb-cross, gdb-cross-sdk 6.8 : Pull in a patch from Ubuntu for gcc-4.3

gcc-4.3 introduces new warnings for certain risky-in-some-situations
behaviors.  Previously we had just sed'd out -Werror from gcc-cross-sdk.
Now pull in a patch from Ubuntu to fix all these warnings and apply to all
gdb 6.8 variants.  Bump PR.
