Seems this comes form the configure step:

	[...] /usr/bin/cmake [...] -DLEMON_C_COMPILER=/home/seiderer/Work/Buildroot/build_rpi0w_mesa_v3d_001/host/bin/ccache /usr/bin/gcc [...]

-       -DLEMON_C_COMPILER=$(HOSTCC)
+       -DLEMON_C_COMPILER="$(HOSTCC)"

 ifeq ($(BR2_TOOLCHAIN_HAS_LIBATOMIC),y)


this changes to

	[...] /usr/bin/cmake [...] -DLEMON_C_COMPILER="/home/seiderer/Work/Buildroot/build_rpi0w_mesa_v3d_001/host/bin/ccache /usr/bin/gcc" [...]

The build succeeds...
