[tlbuild] LuaJIT on OpenBSD

[Mojca Miklavec]

Hi,

Before the switch to C++11 and when compiling with gcc, luajitex
compiled on OpenBSD. Now I switched to clang and I'm getting undefined
references:

/bin/sh ./libtool  --tag=CC   --mode=link clang -Wimplicit

to `_Unwind_DeleteException'

I know we are not shipping binaries, so this in not critical, but I'm
just curious if anyone has any idea.

Thank you,
