Alan Wu 4b7c4bb92e tool/extlibs.rb: Use Exception#message for older rubies
This script runs with BASERUBY, which can be as old as 2.2.x.
Exception#full_message is new in 2.5.0.

I saw a NoMethodError on the AppVeyor CI where BASERUBY is 2.4.6:

What is Ruby?

Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible.

Features of Ruby

  • Simple Syntax
  • Normal Object-oriented Features (e.g. class, method calls)
  • Advanced Object-oriented Features (e.g. mix-in, singleton-method)
  • Operator Overloading
  • Exception Handling
  • Iterators and Closures
  • Garbage Collection
  • Dynamic Loading of Object Files (on some architectures)
  • Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://github.com/ruby/ruby/blob/master/doc/maintainers.rdoc#label-Platform+Maintainers
