The previous approach appended TERMUX_PREFIX to the empty default sysroot, which would render those paths useless if the --sysroot command-line flag was ever set. With this approach, clang reuses much more of the existing sysroot logic and makes it more likely that a passed-in sysroot will work. Also, remove the rpath for alternate architectures, as it wasn't working.
