Indeed, if you want to put libgcc_s.so.1 (or another SONAME on a few
architectures) in DT_NEEDED, you need to do so in a way that does not
involve any previously installed libgcc_s.so.1 (e.g., glibc could build
its own dummy library and use that at static link time, as long as it
doesn't get used later when running tests), so that building glibc with a
static-only compiler continues to work and produce the same results as
building it with a compiler with shared libgcc.
