This is very strange that you see select()! I see just read():
# strace -p8185
Process 8185 attached - interrupt to quit

write(1, "e", 1) = 1

write(1, "i", 1) = 1
read(0, "t", 1) = 1
write(1, "t", 1) = 1
read(0, "\n", 1) = 1
write(1, "\n", 1) = 1

Can you do this: "strace -o logfile ./busybox hush", and then type "exit"
into hush prompt, and send complete logfile to the list?
bzip2 it if it's big. Also attach your .config.
I guess it's a NOMMU build?

No, actially I think toolchain is not a culprit here.
