Current SIGILL handler appears to have weird issues with libluajit on some platform. Considering 6.6 kernel is becoming more common, switch to HWPROBE for better compatibility.

This patchset adds full interpreter and backend support for RISC-V 64 G(IMAFD) with LP64D ABI on Linux, with compile-time/runtime extension support for RVC, Zba, Zbb, Zicond, XTheadBa, XTheadBb, XTheadCondMov and XTheadMac.
Thanks to Mike Pall, LuaJIT is well renowned for its accomplishments and performance in JIT compilers. As an undergraduate interested in RISC-V and compilers, I'm honored to have a chance to contribute to a production compiler. I also want to express my gratitude for the internship opportunity provided by PLCT Lab, ISCAS, which enabled me to this endeavor.
I would greatly value a review of my patch to catch my misses and for a better polish; Your feedback would be invaluable. Thank you for your time and consideration.
