add --trim option for generating smaller binaries

Since I am a big fun of programming languages and compilers, I always follow the latest news about them. I am also a big fun of Julia programming language. I follow the latest commits almost everyday, especially the ones that are related to the compiler. But one of the most important commits that I have ever seen was the one that is related to the --trim option for generating smaller binaries. This feature is the start of a game changer one for the Julia programming language. Finally, I want to share my first tastes of this feature.

In 2024, September 29th, I got up early and turned my computer on. I was excited to see that the legendary pull request was merged.

This pull request introduces a new feature of trimming binary size of the compiled Julia code. Note that the feature is not enabled by default or well-integrated into the compiler. We have now three Julia scripts in the contrib folder of the source code:

These files can be manually downloaded if you are not compiling your own Julia instance from the source code. The juliac.jl script is the main script that is used to compile the Julia code. The juliac-buildscript.jl is a helper script that is used by the juliac.jl script. The julia-config.jl script is used to configure the Julia compiler. I prepared a bash script to download and update these files easily. Here is the script:
