It looks like you've set a lot of these to ignoreFunc. Could you please
walk me through why those system calls are ignorable? Also, with the
stat64 syscall, did you verify that the alignment, etc, of the structure
came out right in the simulated memory? Those have historically been
very finicky to get all the way right, and the problems it causes can be
hard to spot. Even if the binary works, glibc sometimes dumbs itself
down for what it perceives as broken or otherwise inadequate hardware or OS.
