Hello,

# TCWG CI — GDB

- Changed tcwg_gnu-build.sh to apply GDB testsuite patch to avoid infinite loop in tcwg_gdb_check--master-arm jobs, while it isn't committed upstream.

- Started investigating corrupt gdb.sum.1 file in tcwg_gdb_check--master-arm jobs. I can't reproduce it by manually running the CI's "make check-gdb" command line, nor by using ABE. I can reproduce it with tcwg_gnu-build.sh though.

- Came up with validate_failures.py change to make it cope with the corrupt gdb.sum.1 file, while the underlying cause isn't known. Submitted the change upstream.

# TCWG Infrastructure

- Reviewed some Gerrit requests for our CI scripts.

# Misc

- Did some travel planning for Linaro Employee Meeting and GNU Tools Cauldron.
