It calls avr-ld from $PATH instead of the linker as installed in the toolchain and with --prefix. --prefix is not in $PATH but binutils are configured with the same --prefix and installed before GCC way configured. I'd expect that a toolchain installation is self-contained and that if there is a complete toolchain the tools can be called by their absolute paths? Similarly, collect2 in $BUILD calls avr-ld it finds in $PATH instead of the avr-ld installed at --prefix. Is this a bug or a feature? Johann
