Building o32 ELF files for MIPS64 is an exotic configuration that nobody should be using. If o32 is required, then is better if it's built for MIPS 32-bit cores so only 32-bit instructions will be used leading to a more efficient o32 usage.

If your target CPU does not have a Floating Point Unit (FPU)
|
|
or a kernel FPU emulator, but you still wish to support
|
|
floating point functions, then everything will need to be
|
|
compiled with soft floating point support (-msoft-float).
