Miguel Ojeda 70a57b2472 RISC-V: enable building 64-bit kernels with rust support ... The rust modules work on 64-bit RISC-V, with no twiddling required. Select HAVE_RUST and provide the required flags to kbuild so that the modules can be used. The Makefile and Kconfig changes are lifted from work done by Miguel in the Rust-for-Linux tree, hence his authorship. Following the rabbit hole, the Makefile changes originated in a script, created based on config files originally added by Gary, hence his co-authorship. 32-bit is broken in core rust code, so support is limited to 64-bit: ld.lld: error: undefined symbol: __udivdi3 As 64-bit RISC-V is now supported, add it to the arch support table.
