Removing support to xtheadvector might speed up this PR? xtheadvector is well-known for its ghost write bug, and community already has K1 as the alternative to RVV 1.0, maybe there is no real need for xtheadvector, we can just let it go :)

binutils patch for linking rvv and xtheadvector objects together into single binary https://gist.github.com/nihui/91426bd047ba5542d3f2016cda84a0af

append compile flags -mno-riscv-attribute -Wa,-mno-arch-attr to gcc and it works https://gcc.gnu.org/onlinedocs/gcc/RISC-V-Options.html#index-mriscv-attribute https://gcc.gnu.org/onlinedocs/gcc/Assembler-Options.html https://man7.org/linux/man-pages/man1/as.1.html
