环境：Ubuntu 20.04

第一类问题：

$ cd build_dir/host/m4-1.4.17/
$ cd build_dir/host/m4-1.4.17/lib/
$ cd build_dir/host/findutils-4.6.0/
$ cd build_dir/host/findutils-4.6.0/gl/

$ sed -i 's/IO_ftrylockfile/IO_EOF_SEEN/' lib/*.c
$ echo "#define _IO_IN_BACKUP 0x100" >> lib/stdio-impl.h
$ cd build_dir/host/findutils-4.6.0/

sed -i '/unistd/a #include ' lib/mountlist.c

第二类问题：缺少major、minor、makedev 等函数所需的头文件 <sys/sysmacros.h>

$ vim build_dir/host/mtd-utils-1.5.2/mkfs.jffs2.c
$ vim build_dir/host/mtd-utils-1.5.2/ubi-utils/libubi.c
$ vim build_dir/host/mtd-utils-1.5.2/mkfs.ubifs/devtable.c
$ vim build_dir/host/mtd-utils-1.5.2/mkfs.ubifs/mkfs.ubifs.c
$ vim build_dir/host/findutils-4.6.0/gl/lib/mountlist.c
$ vim build_dir/host/squashfs4.2/squashfs-tools/mksquashfs.c
$ vim build_dir/host/squashfs4.2/squashfs-tools/unsquashfs.c

#include <sys/sysmacros.h>

第三类问题：语法错误

$ vim build_dir/host/findutils-4.6.0/gl/lib/mountlist.c
第 36 行，#include 注释掉
