MinGW: Use -static-libgcc when linking a DLL.

Browse Source 
When commit 846e91e022 switched the linker
driver from dlltool/dllwrap to gcc, it became possible for linking to
choose shared libgcc.  Backends having loaded a module dynamically
linked to libgcc can exit abnormally, which the postmaster treats like a
crash.  Resume use of static libgcc exclusively, like 9.3 and earlier.
Back-patch to 9.4.
