[Buildroot] [PATCH] gcc-initial: Add host-elf2flt dependency when BR2_PACKAGE_HOST_ELF2FLT=y

[Axel Lin <axel.lin@ingics.com>]

It's needed for some uClibc combination, link-flat.so which uses elf2flt
pulls in libgcc according to uclibc/Makerules (used in uclibc/libc/Makefile.in).
Thus pull it in for gcc-initial.

This also ensures elf2flt is ready when BR2_PACKAGE_HOST_ELF2FLT=y before
building other packages.

This change is based on Gustavo's comment.
Test build for blackfin looks OK.

This patch replaces my previous patch
"dependencies: Add host prerequisite for elf2flt".
