New issue by tornaria on void-packages repository

https://github.com/void-linux/void-packages/issues/28989

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 5.4.99_1 x86_64 GenuineIntel uptodate FF
* package:  giac-1.5.0.87_3

### Expected behavior
Can choose arbitrary floating point precision:
```
$ giac
[...]
0>> Digits:=30
30
// Time 0
1>> evalf(pi)
3.14159265358979323846264338328
// Time 0
2>>
```

### Actual behavior
Floating point precision is capped at 13 (i.e. double precision, 53 bits)
```
$ giac
[...]
0>> Digits:=30
13
// Time 0
1>> evalf(pi)
3.14159265359
// Time 0
```

### Proposed fix

Add `libmpfr-devel` to `makedepends`.
