linux/version.h not found

[hailmikhail]

See below for error condition.

Instead of shipping some linux headers within this repo, should the script ask for the linux header path? help a user download linux headers?

Enhancement example:

if ! [ -f "$MAC_LINUX_KDK_PATH"/env/include/version.h ] && ! [ -f "$MAC_LINUX_KDK_HEADERS"/linux/version.h ]
then
  echo "Error. Cannot find <linux/version.h>.

Please specify a path to linux headers in MAC_LINUX_KDK_HEADERS env. variable.

Warning. /usr/local/include may host conflicting headers.

Example. If version.h is at /usr/local/include/linux_headers/linux/version.h, do ...

    MAC_LINUX_KDK_HEADERS=/usr/local/include/linux_headers lkmake
"
  exit 1
fi

Disabling speakup is sadly the only way to fix this currently, some of the host tools don't support non Linux-hosts. Including Linux headers may not work since those headers will likely not work properly from Darwin hosts.
