After install libmount-dev, this error is still there.
If we just run:
```
./configure --target-list=aarch64-softmmu --enable-kvm
make -16
```
This works well.
Steps to reproduce:
```
1. ./configure --target-list=aarch64-softmmu --enable-kvm --disable-brlapi --disable-docs --disable-curses --disable-gtk --disable-opengl --disable-sdl --disable-spice --disable-vte --disable-vnc --disable-vnc-jpeg --disable-png --disable-vnc-sasl --disable-auth-pam --disable-glusterfs --disable-libiscsi --disable-libnfs --disable-libssh --disable-bzip2 --disable-lzo --disable-snappy --disable-slirp --disable-libusb --disable-usb-redir --static --disable-qom-cast-debug --disable-libudev --disable-curl --disable-rdma --disable-tools --enable-virtfs --disable-bsd-user --disable-linux-user --disable-sparse --disable-vde --disable-nettle --disable-xen --disable-linux-aio --disable-capstone --disable-virglrenderer --disable-replication --disable-smartcard --disable-guest-agent --disable-guest-agent-msi --disable-vvfat --disable-vdi --disable-qed --disable-qcow1 --disable-bochs --disable-cloop --disable-dmg --disable-parallels --disable-colo-proxy --disable-debug-graph-lock --disable-hexagon-idef-parser --disable-libdw --disable-pipewire --disable-pixman --disable-relocatable --disable-rutabaga-gfx --disable-vmdk --disable-avx512bw --disable-vpc --disable-vhdx --disable-hv-balloon

2.make -j16
```
