[Buildroot] [PATCH] lftp: new package.

["Arnaud Rébillout" <rebillout@syscom.ch>]

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 1/2] Fix posix_fallocate m4 check for cross-compile.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If we're cross-compiling, it's very unlikely that we use old glibc or
+AIX. So we assume that posix_fallocate works.

+Subject: [PATCH 2/2] Check whether posix_fallocate compiles.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+uClibc doesn't provide posix_fallocate as of 0.9.33.2, but some patches
+exist to add this function.
+
+Therefore, the only way to know if posix_fallocate is present is to do a
+compile test.
