works for me on arm strace tracing an arm binary and arm64 strace
tracing an arm64 binary, so please commit.

(it doesn't work on arm64 when tracing a 32-bit process, but that's a
separate issue. do you want me to send you patches in the style of
your stack_t patch from yesterday, or do you prefer to write the
patches yourself and just want me to let you know when i hit a struct
that differs between LP32 and LP64?)
