I would prefer the second item but I'm not familiar with boost.build - I
thought it could evaluate the environment and set the related properties
(if <abi> is not an optional property).
If possible it has to compile and execute a test app:
#if _MIPS_SIM == _ABIO32
#elif _MIPS_SIM == _ABIN32
#elif _MIPS_SIM == _ABI64
#error "unknown MIPS ABI"
I can help a little bit to collect the predefined macros.
