TestGc#test_gc_stress_at_startup failed on my environment, so I check which configure flags affect.

How to reproduce:

./configure cppflags='-DRGENGC_CHECK_MODE -DUSE_RUBY_DEBUG_LOG=1'
make miniruby
env RUBY_DEBUG=gc_stress ./miniruby -v

I can't reproduce with cppflags='-DRGENGC_CHECK_MODE' or cppflags='-DUSE_RUBY_DEBUG_LOG=1'.
