Config.uk: Disable default LIBMUSL_COMPLEX

razvand · unikraft-bot · commit 45c4aa586fa0 · 2023-05-10T17:54:19.000Z
When using Clang to build Musl with complex numbers support, a linking error appears: `__muldc3` symbol is undefined. For Clang, the `__muldc3` symbol is implemented by `libcompiler-rt`. As complex number support is not typically required by applications (that use Musl), this commit disable it by setting the `LIBMUSL_COMPLEX` option to `n`. If required, the application will enable `LIBMUSL_COMPLEX` (set it to `y`) and, in the case of Clang, add `libcompiler-rt`.
