--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
1. Need large model crtbegin*.o and crtend*.o.
2. Need large mode libgcc.a, libgcc_eh.a and libgcov.a.
3. Need large mode lib*.a if we want to link with lib*.a
4. Need the large model libc.a if we want to support large model static
executable.

libc_nonshared.a and crt1.o from glibc need build changes even for dynamic
linking.
