As documented in https://gcc.gnu.org/install/build.html
you need a matching native GNAT compiler to build a GNAT cross compiler.
If I understood properly, you are using a GCC 8.3.0 as the host compiler
to build a GNAT cross compiler, which indeed won't work: you need to first
build a native matching compiler and then use this matching compiler to build
the cross.
