open*(2) compat fixes (s390, arm64)
The usual rules for open()/openat()/open_by_handle_at() are 1) native 32bit - don't force O_LARGEFILE in flags 2) native 64bit - force O_LARGEFILE in flags 3) compat on 64bit host - as for native 32bit 4) native 32bit ABI for 64bit system (mips/n32, x86/x32) - as for native 64bit There are only two exceptions - s390 compat has open() forcing O_LARGEFILE and arm64 compat has open_by_handle_at() doing the same thing. The same binaries on native host (s390/31 and arm resp.) will *not* force O_LARGEFILE, so IMO both are emulation bugs. Objections? The fix is obvious...
