busybox: remove i386-specific build flags
busybox tries to be smart and passes a number of additional flags to the compiler. Unfortunately, the i386-specific flags break ABI compatiblity with libc. Fixes busybox crashes observed on x86-generic with GCC 7. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>
