Currently, rust fails to build for mipsel_24kc+24kf with "opcode not supported on this processor: mips1 (mips1)" errors when building libunwind. Because mipsel_24kc+24kf is hard-float, a certain section of src/llvm-project/libunwind/src/UnwindRegistersRestore.S is selected to be compiled; the instructions in this section require MIPS II. mipsel_24kc+24kf is compiled for MIPS32 Release 2 (MIPS32 is based on MIPS II), but the C flags used to select this architecture were not passed to the rust bootstrap (to be passed back to gcc). This passes the C flags to rust bootstrap to fix this compile error. This also adds PKG_BUILD_FLAGS:=no-mips16 as attempting to generate MIPS16 code leads to a different compile error.

|
|
Rust is a multi-paradigm, general-purpose programming language designed for performance
|
|
and safety, especially safe concurrency. Rust is syntactically similar to C++, but can
|
|
guarantee memory safety by using a borrow checker to validate references.
