Gem commonmarker 1.x fails to compile native extensions with rust

[rwstauner]

Using the latest commit and a jvm-ce build

truffleruby 24.1.0-dev-00307c24, like ruby 3.2.2, GraalVM CE JVM [x86_64-linux]

with the latest gem version (1.0.4)
installation fails due to several items missing from RbConfig::CONFIG:

error: failed to run custom build command for `rb-sys v0.9.85`

Caused by:
  process didn't exit successfully: `/home/spin/.gem/truffleruby/3.2.2/gems/commonmarker-1.0.4/ext/commonmarker/target/release/build/rb-sys-4475e29d236d2359/build-script-main` (exit status: 101)

If I add these values (and use something like export TRUFFLERUBYOPT=-r$PWD/config) I get past those issues.

RbConfig::CONFIG["MAJOR"] = "3"
RbConfig::CONFIG["MINOR"] = "2"
RbConfig::CONFIG["TEENY"] = "1"
RbConfig::CONFIG["PATCHLEVEL"] = "1"
RbConfig::CONFIG["archincludedir"] = "/tmp/archincludedir"

Then I get other errors:
