Make asan more closely match clang behavior.
Always link libm with asan. Hasn't been a problem before because ASAN
was only ever used when libc++ was as well, which already links libm.
Pass --no-as-needed for host modules.
These aren't needed for the target builds because the target uses the
shared RTL.
