[Buildroot] [PATCH 03/20] elf2flt: fix build when zlib is not installed on the host

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.

Note: I already have a patch that converts elf2flt to the package
infrastructure, but I am waiting to have the patches to make the
entire internal toolchain logic use the package infrastructure to send
them.
