Subject: [PATCH] extconf.rb: use Rbconfig::CONFIG instead of mkmf CONFIG
In mkmf.rb CONFIG is defined as CONFIG is defined as RbConfig::MAKEFILE_CONFIG
and RbConfig::MAKEFILE_CONFIG is almost same as RbConfig::CONFIG
except that RbConfig::MAKEFILE_CONFIG uses reference for other variables.
Using CONFIG in extconf.rb causes error with ruby3.2 because now
CONFIG['host_os'] uses reference for target_os variable, and extconf.rb
expects that this variable is all expanded. So instead, use RbConfig::CONFIG .
Closes #30
