Can we build with MIPS soft float ABI

[targos]

I've been trying to build the master branch for the Atheros AR9331 that has no hardware fpu. I have no problem to cross-compile everything but in the end node fails to run because V8 tries to execute illegal instructions.

According to https://github.com/paul99/v8m-rb/wiki/Building-v8-for-MIPS-with-GYP#softfloat-support-deprecated softfloat is not supported by V8 anymore. Is there anything I can do about it at compile time or should the configure option --with-mips-float-abi be removed ?

--with-mips-float-abi controls the calling convention for functions that take or return floating-point values. V8 still supports the soft-float ABI, the change in V8 3.18 is that it no longer supports a 'no floating point' mode.

The assumption now is that your kernel will emulate floating point instructions when needed.

Assuming this can be closed.
