After removing this flag, we can see some FPU code remains there: gcc-11.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/display_mode_lib.o uses hard float, drivers/gpu/drm/amd/amdgpu/../display/dc/clk_mgr/dcn301/vg_clk_mgr.o uses soft float Therefore, remove the -mno-gnu-attribute flag for dcn301/powerpc and move FPU-associated code to DML folder.
