I don't think pdfstudio depends on libgccjit. If it did, that would
be a license violation. Unlike the other libraries in gcc,
libgccjit is licensed GPLv3 with no exceptions, since libgccjit
contains the entire compiler.
I wasn't able to build pdfstudio2022 prior to this PR due to openjdk
breakage. However I did download and extract the `.deb` used, and
ran this command, which produced no outputs:
```
find . -name \*.so -exec ldd {} \; | grep libgccjit
```
Maybe somebody confused `libgccjit` with (may it rest in peace)
`libgcj`?
