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

When SDKMACHINE is set to "i686", nativesdk-ninja is compiled as a
32-bit binary. Without large file support (LFS), ninja's internal stat()
call uses a 32-bit struct stat, which results in EOVERFLOW on filesystems
that report inode numbers larger than 2^32 (e.g. container overlay
filesystems).

Add -D_FILE_OFFSET_BITS=64 to CXXFLAGS for nativesdk builds to enable
LFS, ensuring stat() uses 64-bit types regardless of host word size.
