Yes, a lot of things have changed, fixing design errors and adding new
functionality to support building monolithic systems that coexist with
non-monolithic ones, avoiding name collisions and many other things
that made the previous asdf:make-build of little use.

This is a problem with ASDF itself, not really the ECL environment nor
our extensions. ASDF captures all compiler conditions (i.e. errors and
warnings) and thus will prevent you from entering the debugger. I do
not remember whether there are options to enter the debugger from
ASDF, but you may try setting c::*compiler-break-enable* to T before
building anything

I cannot tell you just like that, without knowing the platform and
your configuration settings. But the ANSI standard function
COMPILE-FILE-PATHNAME exists for this reason. Just pass it the same
type as you would pass to make-build.
