[ACTIVITY] weekly status

I mainly worked on the atomic memory operations blueprint/item: * posted an updated patch for #643171 on the libc-ports ml after running the glibc testsuite natively on the vexpress * continued to learn about the ARM instructions involved :) * started to write some gcc testcases that scan the asm output of the __sync builtins (mainly to detect differences between the gcc versions - not sure how useful those tests would be for upstream as the sequences may easily change)
