clang uses incorrect library order

[androm3da]

When linking programs with eld, we get a link error like below:

Error: /inst/clang+llvm-19.1.0-cross-hexagon-unknown-linux-musl/x86_64-linux-gnu/bin/../target/hexagon-unknown-linux-musl//usr/lib/libc.a(scalbn.lo)(.text.scalbn+0x3c): undefined reference to `__hexagon_muldf3'

libc has references to the clang_rt builtins library, so the order of the libraries should be reversed.
