sim: testsuite: add dedicated flag for init toolchain tests

Browse Source 
As we setup more reliable CC_FOR_TARGET variables for each target, the
bfin way of overriding it to stuff custom CFLAGS doesn't scale well.
Add a dedicated CFLAGS_FOR_TARGET_init setting that each set of tests
can setup if they want to add custom options.
