[PATCH v2 4/8] arm64: nvhe: add bee-headers support

[Daniel Gomez via B4 Relay]

From: Daniel Gomez <da.gomez@xxxxxxxxxxx>

endian.h header is not provided by default in macOS. Use pkg-config with
the new development package 'bee-headers' [1] to find the path where the
headers are installed.

[1] Bee Headers Project links:
https://github.com/bee-headers/headers
https://github.com/bee-headers/homebrew-bee-headers

It requires to install bee-headers Homebrew Tap:

  brew tap bee-headers/bee-headers
  brew install bee-headers/bee-headers/bee-headers
