Wrong, no.  harder yes. C compilers have mature cross compiler build chains
including stage aware test suites and the like. When a tool is it's own
build dependency bootstrapping it on a new platform gains a hard
requirement on cross compiling rather than it being a thing for special
cases like platforms that cannot compile the tool. This makes the life of
distribution maintainers harder too, since cross arch platform
bootstrapping becomes even more manual.
