[Buildroot] [PATCH] dependencies: Add host prerequisite for elf2flt

[Axel Lin]

This ensures elf2flt will be built when BR2_PACKAGE_HOST_ELF2FLT=y before
building other packages.

I don't have a blackfin platform, only test build this for blackfin.
Without this patch, the first time build will result in ELF binary because
busybox is built before elf2flt.
With this path, the result looks good, it produces BFLT executable for busybox.
