libffi: fix the build for MIPS soft-float with recent compilers Recent MIPS compilers have an stricter agreement between the compiler and the assembler on the ABI. The compiler now passes -msoft-float to the assembler where it previously did not. libffi uses MIPS hard-float instructions so when we try to build it for soft-float using a recent compiler it fails because of the explained above. This package should be fixed in order to add support for soft-float. In the meantime we can add a little hack in order to be able to build it for soft-float. Basically we add ".set hardfloat" so the assembler will not disable the hard-float instructions. The build will of course include some hard-float bits which shouldn't exist in a soft-float build, and that may cause runtime problems. But that's what we already had before and we had lived with it. We choose to apply this temporary fix because it only affects MIPS soft-float builds. Otherwise we would need to disable libffi and recursively all the packages depending on it (python, libglib2...) for MIPS soft-float, which would be a bit overkill.

Subject: [PATCH] libffi: enable hardfloat in the MIPS assembly code
This way it will be possible to build it for soft-float. This is only a
temporary fix. The package needs to be fixed properly.
