In a regular gcc installation there is libgcc.a, libgcc_s.so and

In a regular link libgcc.a and libgcc_s.so are used.
In a static link libgcc.a and libgcc_eh.a are used.

But when gcc is built with --disable-shared, there is no
libgcc_eh.a. Everything is in libgcc.a.

This means that clang has to know if the gcc installation is static or
not. Currently it assumes it is not.
