Same when just copying klibc-m13AniKHUCMUNN8mXSUhIi8CUSA.so out
of libklibc_2.0.12-1_armhf.deb into /lib/ and extracting fstype
from klibc-utils_2.0.12-1_armhf.deb… however it works both on a
real-metal ARM box (amdahl.d.o) and a statically(!) linked mksh
against klibc :/

My guess here is that it’s, as usual, the fault of qemu-user,
which has multiple outstanding emulation bugs, some of which
affecting klibc-built binaries especially, though this, since
a statically linked mksh works, is probably an issue with how
qemu-user handles .interp *shrug*

Since your one-stage debootstrap succeeds, can you not do the
remaining steps booting into the image-under-preparation and
run them there? Here, qemu-system-armhf should probably suffice.
I know, it’s just as a workaround, until the people in question
figure out why this happens.
