Bug#1025649: love: undefined symbol: PHYSFS_getSearchPath

[Premek]

Package: love
Version: 11.4-1
Severity: normal
X-Debbugs-Cc: premysl.vyhnal+bugreport at gmail.com

Some love programs using FFI crash with the error message below.

$ cat main.lua
local ffi = require'ffi'
ffi.cdef("bool PHYSFS_unmount(const char *path);")
ffi.C.PHYSFS_unmount("xyz")

$ love .
Error: main.lua:3: /lib/x86_64-linux-gnu/libluajit-5.1.so.2: undefined symbol:
PHYSFS_unmount
stack traceback:
        [love "boot.lua"]:345: in function <[love "boot.lua"]:341>
        [C]: in function '__index'
        main.lua:3: in main chunk

        [love "boot.lua"]:355: in function <[love "boot.lua"]:348>
        [C]: in function 'xpcall'

Running the same program with love compiled from source does not print any
error.
