Of the ones that are not symlinks, I have /lib/x86_64-linux-gnu/libc-2.28.so, /sysroot/lib/amd64/libc.so.1, and /sysroot/lib/libc.so.1. So I think I have glibc 2.28 based on the first file, but I am not certain. My gcc is gcc 4.7.4. I have multiple unistd.h files on my build machine, but none of them have setresgid (I checked by running find as root to find all the unistd.h files, and then I grepped each of them for setresgid). Is there a minimum libc version that is needed to compile the boostrap?
