Thanks to klibc lacking x32 support, /bin/sh is an amd64
binary on x32 machines with mksh’s lksh as /bin/sh, when
lksh is built with klibc (which is the default in Debian),
because klibc:x32 actually builds amd64 binaries.
I’d suggest this instead, which is actually dependent on
the compiler used¹:
x86_64:Linux:*:*)
eval "$set_cc_for_build"
if echo __ILP32__ | $CC_FOR_BUILD -E - 2>/dev/null \
| grep -q __ILP32__
then
echo "$UNAME_MACHINE"-pc-linux-"$LIBC"
else
echo "$UNAME_MACHINE"-pc-linux-"$LIBC"x32
fi
exit ;;
① This will detect klibc builds as amd64 instead of x32,
but that’s fine; it will detect regular x32 builds
correctly.
