So you may just want to make this a configure-time option.
pkirchner has informed me /proc/kcore returns the correct information in this case on MIPS, and I've also received x86-32/64 confirmation.
64-bit in 32-bit ELF: <pkirchner:#mipslinux> it does say abi=674 mips1 not 32bitmode not fp32 DecStation 5000/200: /proc/kcore: file format elf32-tradlittlemips
