lua compilation and tmpnam

[richfitz]

Since rlite includes lua there are more tricks in compilation. I see

gcc -std=gnu99 -shared -Wl,-soname,libhirlite.so.0.1 -o libhirlite.so  ../deps/lua/src/lapi.o ../deps/lua/src/lcode.o ../deps/lua/src/ldebug.o ../deps/lua/src/ldo.o ../deps/lua/src/ldump.o ../deps/lua/src/lfunc.o ../deps/lua/src/lgc.o ../deps/lua/src/llex.o ../deps/lua/src/lmem.o ../deps/lua/src/lobject.o ../deps/lua/src/lopcodes.o ../deps/lua/src/lparser.o ../deps/lua/src/lstate.o  ../deps/lua/src/lstring.o ../deps/lua/src/ltable.o ../deps/lua/src/ltm.o ../deps/lua/src/lundump.o ../deps/lua/src/lvm.o ../deps/lua/src/lzio.o ../deps/lua/src/strbuf.o ../deps/lua/src/fpconv.o ../deps/lua/src/lauxlib.o ../deps/lua/src/lbaselib.o ../deps/lua/src/ldblib.o ../deps/lua/src/liolib.o ../deps/lua/src/lmathlib.o ../deps/lua/src/loslib.o ../deps/lua/src/ltablib.o ../deps/lua/src/lstrlib.o ../deps/lua/src/loadlib.o ../deps/lua/src/linit.o ../deps/lua/src/lua_cjson.o ../deps/lua/src/lua_struct.o ../deps/lua/src/lua_cmsgpack.o ../deps/lua/src/lua_bit.o rlite.o page_skiplist.o page_string.o page_list.o page_btree.o page_key.o page_multi_string.o page_long.o type_string.o type_list.o type_set.o type_zset.o type_hash.o util.o restore.o dump.o sort.o pqsort.o utilfromredis.o hyperloglog.o sha1.o crc64.o lzf_c.o lzf_d.o scripting.o rand.o hirlite.o
../deps/lua/src/loslib.o: In function `os_tmpname':

which seems ominous. I've out worked out tmpnam is being used when rlite is compiled by itself or if mkstemp is being used. The lua target is ansi (see lua: target in src/rlite/Makefile) and that defines -DLUA_ANSI. If LUA_USE_LINUX (even on OSX) is defined that defines LUA_USE_POSIX and that defines LUA_USE_MKSTEMP which sets up using the mkstemp.

I can get local compilation and compilation on docker working, but I'm seeing issues on travis so I've rolled the version back a little.
