Ok, then what you're testing is actually whether you're using sjlj or dw2 unwinding. config/i386/cygming.h will ensure that this is the same as testing TARGET_BI_ARCH and TARGET_64BIT_DEFAULT.
Then you can just pass EH_MODEL or SHLIB_SONAME down to libgcc via libgcc.mvars, and look at it in libgcc/config.host to pick the appropriate header.
