[Buildroot] [git commit] elf2flt: fix build when zlib is not installed on the host

commit: http://git.buildroot.net/buildroot/commit/?id=85e3090a92e13b7afc426cb2d9189bbe8d2adaf4
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

For a reason that's fairly unclear to me, Peter added a '-lz' link
flag to the elf2flt.mk build in d5664ee99 ("elf2flt: fix link").

However, the zlib library may not necessarily be installed on the host
machine, so we should depend on host-zlib, and pass the appropriate
LDFLAGS. This is what this patch does.
