rice-c/build.rs runs bindgen without any target flags, so libclang
parsed the build host headers in /usr/include, which fails when cross
compiling, e.g. for riscv64/musl:

  /usr/include/bits/floatn.h:97:9: error: __float128 is not supported on this target

Pass the target arch flags, sysroot and triple via
BINDGEN_EXTRA_CLANG_ARGS, as thin-provisioning-tools does.
