@bartoldeman I hadn't looked into those yet (also because it seems they're not really used?), and just applied the same kind of fix that was also done for aarch64. But you're right, they will not work either, so I can remove them as well. edit: done in 37858f1. |

While trying to build GMP (which has
precise: Trueintoolchainopts), the configure step failed because-mno-recipis not supported on RISC-V, similar to Arm (see #3425).@julianmorillo checked with a compiler expert, and he recommended to use
-fno-reciprocal-math. This is a generic flag and used by default, so without a sensible alternative, I've just removed the flags for these toolchain options. It will then basically ignore theprecise: Trueand use the default flags.
