configure: error: cannot guess build type; you must specify one

解决

在 PKGBUILD 的 prepare() 中添加：
```
autoupdate
autoreconf -fiv
```

编译构建，解决。

报错信息

make[1]: Entering directory '/build/gnuchess/src/gnuchess-6.2.9/man'
/bin/sh '/build/gnuchess/src/gnuchess-6.2.9/missing' help2man --name='GNU Chess' --info-page='gnuchess' ../src/gnuchess -o gnuchess.1
/build/gnuchess/src/gnuchess-6.2.9/missing: line 81: help2man: command not found
WARNING: 'help2man' is missing on your system.
         You should only need it if you modified a dependency of a man page.
         You may want to install the GNU Help2man package:
         <https://www.gnu.org/software/help2man/>
make[1]: *** [Makefile:560: gnuchess.1] Error 127
make[1]: Leaving directory '/build/gnuchess/src/gnuchess-6.2.9/man'
make: *** [Makefile:518: all-recursive] Error 1

解决

阅读报错消息是 help2man: command not found，没有找到命令，下文 WARNING: 'help2man' is missing on your system 也提示可能本机缺少 help2man 这个包。

将 help2man 加入 PKGBUILD 的 makedepends 中，参与构建 gnuchess 的编译。
```
makedepends=('help2man')
```

编译构建，解决。

思考

在打包成功的日志后发现如下输出：
```
Checking PKGBUILD
Checking gnuchess-6.2.9-2-riscv64.pkg.tar.zst
gnuchess W: Dependency included and not needed ('help2man')
==> Running checkpkg
  -> Checking packages
==> No soname differences for gnuchess.
```
gnuchess W: Dependency included and not needed ('help2man')：包含，但不需要 help2man 依赖。

是否可以将 depends 替换成 makedepends，将 help2man 降级为编译时依赖，仅仅参与编译？

解决：后续测试通过，并且没有上述那句话。

Checking PKGBUILD
Checking gnuchess-6.2.9-2-riscv64.pkg.tar.zst
==> Running checkpkg
  -> Checking packages
==> No soname differences for gnuchess.

综合解决方案

向 gnuchess 上游汇报 config.guess 过老的问题，然后遵循上述报错解决的步骤。
