Link-time optimization requires close coordination between the compiler
and the linker, so not all combinations of compiler and linker support
it.
Previously, when compiling with Clang, we checked only for lld. With
this commit, we expand the list of supported linkers we check for.
Closes #5536
Merge branch '5536-more-supported-linker-ids' into 'main'
