I think your "-O0 -rdynamic" options are coming from someplace outside
of configure. I'm also on Arch Linux and I see:

configure:8924: result: ccache i686-w64-mingw32-gcc
configure:8940: checking whether ccache i686-w64-mingw32-gcc works
configure:8953: ccache i686-w64-mingw32-gcc -c -g -O2  conftest.c >&5

I also noticed the configure line numbers are different, which seems
strange as configure is tracked by git. The string 'rdynamic' doesn't
appear in Wine's configure script.
