Link failed due to --gc-sections begin enabled by default

[d-musique]

When trying to link any program, the error message below appears.

This is DMD64 D Compiler v2.112.0-beta.1 running on Linux. The compiler command used as the linker is clang, which in turn invokes lld.

The problem is resolved if dmd explicity passed --no-gc-sections to the linker. see https://github.com/OpenMandrivaAssociation/dmd/blob/88afa4d72ed721e5b1175e2fff11be7bc5d63320/no-gc-sections.patch
