Hum, after thinking a bit more about this, why would we change GNU_HOST_NAME? It sounds strange to include "buildroot" in the name of the build machine tuple. Adding it to the target machine tuple would seem much more appropriate, no? I.e: GNU_TARGET_NAME=$(ARCH)-unknown-linux-$(LIBC)$(ABI) changed to: GNU_TARGET_NAME=$(ARCH)-buildroot-linux-$(LIBC)$(ABI) No? Thomas

When compiling for the same architecture and libc as the host, GNU_TARGET_NAME and GNU_HOST_NAME are equal. configure scripts use these to detect cross-compilation, and will decide that we're doing native compilation. This may trigger running of executables, which fail because of missing libraries in the host environment. To solve this, set the vendor part in GNU_HOST_NAME to buildroot. This problem exists for instance in xserver_xorg-server on x86_64. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> --- v2: -buildroot- instead of -buildroot_cross-, as suggested by ThomasP.
