ext: hal: altera: Add ifdef protection for __LINUX_ERRNO_EXTENSIONS__

__LINUX_ERRNO_EXTENSIONS__ gets defined in HAL/inc/sys/alt_errno.h, however we also need to define this if we are building with newlib. So add a simple ifdef guard to only define __LINUX_ERRNO_EXTENSIONS__ if its not defined already. Signed-off-by: Kumar Gala <[email protected]>
