Makefile: add large file support (LFS)

Large file support (LFS) in recent C libraries allows 32 bit applications to
create large files with file length values > 0x7FFFFFFF when the filesystem
supports it.

This patch adds large file support to the Makefile, if you don't want LFS use
the autotools version and call configure like this:

    ./configure --disable-largefile
