Commit 2570d553ef31f5a8df408f1cdc7fa32f7c5d947f

Fix C Lua modules not loading on Unix-like systems
Did attempt to escape with single quotes like this:
LDFLAGS="$LDFLAGS '-Wl,--export-dynamic-symbol=lua_*'"
but it broke compilation because the quotes were escaped. Anyway, the
probability of a file starting with `-Wl,--export-dynamic-symbol=lua_`
or `-Wl,--export-dynamic-symbol=luaL_` is rather low.

Thanks to Steven Xu (a.k.a. stevenxxiu).

5 # SYNOPSIS
6 #
7 # AX_CHECK_LINK_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
8 #
9 # DESCRIPTION
10 #
11 # Check whether the given FLAG works with the linker or gives an error.
12 # (Warnings, however, are ignored)
13 #
14 # ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
15 # success/failure.
16 #
17 # If EXTRA-FLAGS is defined, it is added to the linker's default flags
18 # when the check is done. The check is thus made with the flags: "LDFLAGS
19 # EXTRA-FLAGS FLAG". This can for example be used to force the linker to
20 # issue an error when a bad flag is given.
21 #
22 # INPUT gives an alternative input source to AC_LINK_IFELSE.
23 #
24 # NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
25 # macro in sync with AX_CHECK_{PREPROC,COMPILE}_FLAG.
