Testing the changes

• I tested the changes in this PR: YES

Local build testing

• I built this PR locally for my native architecture, (x86_64-glibc)

Currently build fails with

=> j-9.4.3_1: running post-install hook: 11-pkglint-elf-in-usrshare ...
=> ERROR: j-9.4.3_1: ELF files found in /usr/share:

=> ERROR:    /usr/share/j/tools/regex/libjpcre2.so
=> ERROR: j-9.4.3_1: cannot continue with installation!

Now it builds on my machine and works properly. (x86_64-glibc)
