Build failure on Windows cross compilation for aarch64-linux

[barakugav]

Im compiling using 'cargo build' with '--target=aarch64-unknown-linux-gnu', and the compilation fails as it doesn't detect bazel. I have installed bazel and added it to path on windows. As the script ./configure seems to run from 'bash' i have installed bazel in the bash too, using './bazel-5.3.1-installer-linux-x86_64.sh'.

Also the ./configure file had to be changed using dos2unix, as it was run from bash.

Full log:
