[Devel] [RFC PATCH] Make AT_VECTOR_SIZE_ARCH 2 for x86-32

[Serge E. Hallyn]

[ RFC:  Am I on crack? ]

Both x86-32 and x86-64 with 32-bit compat use ARCH_DLINFO_IA32,
which defines two saved_auxv entries.  But system.h only defines
AT_VECTOR_SIZE_ARCH as 2 for CONFIG_IA32_EMULATION, not for
CONFIG_X86_32.  Fix that.
