I get the following error when building on an NFSv3 filesystem:
% make -j8
GEN aarch64-softmmu/config-devices.mak.tmp
GEN config-host.h
[snip]
GEN qmp-marshal.c
GEN aarch64-softmmu/config-devices.mak
cp: preserving permissions for ‘aarch64-softmmu/config-devices.mak.old’:
Operation not supported
make: *** Deleting file `aarch64-softmmu/config-devices.mak'
GEN qapi-types.c
[snip]
CC scsi/qemu-pr-helper.o
make: *** No rule to make target `config-all-devices.mak', needed by
`subdir-aarch64-softmmu'. Stop.
make: *** Waiting for unfinished jobs....
Ideally you would only build on a filesystem with proper support, but I haven't
been able to find a reason why preserving exact permissions is important in
this case.
