NetBSD from HEAD-llvm does not ship with libgcc_s.so.1, so one has to
manually provide it in order to run foreign binaries built with GCC.
Where did the user get libgcc_s.so.1 from?
I have rust-1.66.1 (not the latest) on my HEAD-llvm amd64 system.
Base is 9.99.107 (again not the latest) and libgcc_so.so.1 is from
9.99.99. So if this broke it did so fairly recently.

Until clang ships as part of a formal release (with NetBSD release
binaries) I think it is OK to require users to manually provide
libgcc_s.so.1.
