Since you need to check each of them manually anyways, simply compile
you kernel with "make V=1".
But note that options like -ffreestanding, -msoft-float or -mregparm=3
will most likely not make any sense (and actually do harm) in your user
space application ("info gcc" gives you more information on them).
Besides this, at least the cpu options might not be optimal for
userspace since the kernel doesn't use options like -march=athlon-xp
that bring improvements only for floating point maths.
