LOG: Reapply [lld][flang] Add exceptions for Flang runtime libraries on MinGW.

When linking a shared library with Flang on MinGW, the functions from the
Flang runtime are exported from the shared library. When trying to link an
executable to that library using Flang, the linker errors out because the
functions from the runtime conflict with the functions exported from the
shared library.

Add the Flang runtime libraries to the list of libraries for which no
symbols are exported.

Reapplying the patch with the git author name corrected.
