Eclipse didn't find ''make'' (that was the second error in your error-list)
loacte your compiler and check if a there is a ''Make'' avaliable (may be its ''cs-make'' so you just need to change the build-command in the eclipse-project settings) If you have no ''make'' then search and install ''msys'' (this should also solve your missing ''echo'') and select in the package-downloader ''make'' and ''msys-coreutils''. If you won't add the PATH to your environment (because its need a restart), the simplest way is to start Eclipse everytime over a batch-File. E.g. : PATH=%cd%\..\gcc-arm-none-eabi-win32\bin;%PATH% PATH=%cd%\..\yagarto-tools\bin;%PATH% PATH=%cd%\..\mingw\msys\1.0\bin;%PATH% start eclipse.exe
