Android ndk: Host 'awk' tool is outdated. Please define host_awk to point to gawk or Naw

After cygwin is deployed, compile the sample that comes with ndk and report the following error: "android ndk: Host 'awk' tool is outdated. Please define host_awk to point to gawk or nawk! "Ndkcomes with an awk.exe, and the host 'awk' tool is outdated. It has expired. Find the solution, the most direct way is to ndk host directory -- D: \ Android \ android-ndk-r7 \ prebuilt \ windows \ bin \ awk.exe
Delete this expired awk.exe. In this way, when the awk cannot be found, the default awk of cygwin will be called to parse the awk file. Then OK.
