From: Peter Tatrai <peter.tatrai.ext@siemens.com>

When SDKMACHINE is set to i686 or i586, nativesdk binaries are compiled
as 32-bit. Without -D_TIME_BITS=64 and -D_FILE_OFFSET_BITS=64, stat()
and time-related syscalls use 32-bit types, causing EOVERFLOW on
filesystems with large inode numbers (e.g. container overlay filesystems)
and Y2038 issues.

Add SDK_CC_ARCH appends for class-nativesdk:i686 and class-nativesdk:i586
using GLIBC_64BIT_TIME_FLAGS, mirroring how target architectures are
handled.
