The attached patch applied over the current ebuild exports the toolchain variables to make sure nfs-utils is built using the right named tools, allowing to crosscompile the package and to cross-distcc it. Thanks, Diego
Created attachment 73069 [details, diff] Ebuild patch
most of those vars arent needed, and nfs-utils doesnt cross-compile anyways (hits errors with rpcgen since it tries to execute it after building with target CC)
