The Makefile generated by extconf.rb has changed in Ruby 3.0. Therefore, when using Ruby 3.0, the optimization flags are not set properly and it reduced the performance. This patch will set optimization flags in compiling properly. - Here is Ruby 2.7 Makefile result: ``` CXXFLAGS = $(CCDLFLAGS) -g -O2 -std=c++1z -Wno-register $(ARCH_FLAG) ``` - Here is Ruby 3.0 Makefile result: ``` CXXFLAGS = $(CCDLFLAGS) -std=c++1z -Wno-register $(ARCH_FLAG) ```

Based on the fix by Watson1978 in PR #24. Ruby 3.0+ no longer includes $(optflags) in CXXFLAGS automatically, causing simdjson to compile without -O2. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
