crossbuild-essential-riscv64 - 12.12 main

If you do not plan to cross build Debian packages, you don't need
this package. Starting with sbuild (>= 0.63.0) this package is
required for cross building Debian packages in a chroot.
.
This package contains an informational list of packages which are
considered essential for cross building Debian packages. This
package also depends on the packages on that list, to make it easy to
have the cross-build-essential packages installed.
.
If you have this package installed, you only need to install whatever
a package specifies as its build-time dependencies to cross build the
package. Conversely, if you are determining what your package needs
to build-depend on, you can always leave out the packages this
package depends on.
