New issue by tleydxdy on void-packages repository

https://github.com/void-linux/void-packages/issues/18816

Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:  
  `Void 5.4.17_1 x86_64-musl GenuineIntel uptodate rrnFFF`
* package:  
  `mdocml-1.14.5_3`

### Expected behavior
Build pass
### Actual behavior
Build fails with 
```
make: echo: No such file or directory
```
Line 44 in `builddir/mandoc-1.14.5/configure` seems to be causing it
### Steps to reproduce the behavior
```
./xbps-src -N pkg mdocml
```
