I do.  For many cross targets, you start with nothing, so you can't do
link tests until after the C library is built, but you can't build the
C library until the compiler is built, etc.

And many of the tests are "run this" tests; compiling and linking
isn't always sufficient.

Um, no.  I do cross compilers starting with only a native compiler and
the original sources.  Note that writing cross development tools is my
day job - I do this all the time.
