I tried to build minimal busybox-only project for using as initramfs. I use
external buildroot toolchain. The buildroot copy the .so libraries from
external toolchain to the target dir unconditionally. But I build busybox
statically and don't need shared libraries (the size of resulted image is too
big with unneeded libraries).
The patch use BR2_PREFER_STATIC_LIB to find out if the project prefer
static linking and if the static linking is preferred don't copy shared
libraries to the target dir.
