Feature #14656: Improve mkmf error message when ruby.h is missing

Description
Without the development tools, trying to install most gems results in the following error :
mkmf.rb can't find header files for ruby at #{$hdrdir}/ruby.h Copy-pasting the error into a search engine yields numerous versions of the same solution : installing the ruby development environment (package ruby-dev or ruby-devel on most Linux distributions) solves the issue.
Maybe the error message could hint at this solution? I found the following line further down in the same file that could be added after the current error message :
You have to install development tools first.
