lftp: new package

LFTP is a sophisticated ftp/http client, and a file transfer program
supporting a number of network protocols. Like BASH, it has job
control and uses the readline library for input. It has bookmarks,
a built-in mirror command, and can transfer several files in parallel.
It was designed with reliability in mind.

+Subject: [PATCH] Fix posix_fallocate m4 check for cross-compilation.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If we're cross-compiling, we can't test if the code run, we can only
+test that it compiles and links. If it does, assume posix_fallocate
+works, because cross-compilation for AIX or old glibc is unlikely.
