make -j8编译失败在aarch64平台

[Tom-python0121]

我遇到一个问题，关于在centos8 aarch64平台移植xavs2出现的问题，如下所示：

[root@centos8 linux]# ./configure --prefix=$build_dir/avs2_lib --enable-pic --enable-shared
platform:      AARCH64
byte order:    little-endian
system:        LINUX
cli:           yes
libxavs2:      internal
shared:        yes
static:        yes
asm:           yes
interlaced:    yes
avs:           no
lavf:          no
ffms:          no
mp4:           no
gpl:           yes
thread:        posix
opencl:        no
filters:       crop select_every
lto:           no
debug:         no
gprof:         no
strip:         no
PIC:           yes
bit depth:     8
chroma format: all

You can run 'make' or 'make fprofiled' now.
[root@centos8 linux]# make -j8

现在我看到configure以及Makefile里头关于这方面的描述：
vim configure:

这里中间缺少了拉取common/aarch64的步骤。
vim Makefile:

由于common/aarch64里头没有这些文件，导致编译失败。

你能够告诉我如何才能够下载到上面那些文件么？（包括davs2也报这样的错误）
