Hey folks,

I'm trying to run bpftop for Android. However, cross build --target aarch64-linux-android complains about missing dependencies:

  Package libelf was not found in the pkg-config search path.
  Perhaps you should add the directory containing `libelf.pc'
  to the PKG_CONFIG_PATH environment variable
  No package 'libelf' found
  Package zlib was not found in the pkg-config search path.
  Perhaps you should add the directory containing `zlib.pc'
  to the PKG_CONFIG_PATH environment variable
  No package 'zlib' found
Full log
