Linking with the 64-bit crt0.o Startup File
In 32-bit mode, you must always include crt0.o on the link line.
In 64-bit mode, you must include crt0.o on the link line for all fully
archive links (ld -noshared) and in compatibility mode (+compat). You
do not need to include the crt0.o startup file on the ld command line
for shared bound links. In 64-bit mode, the dynamic loader, dld.sl, does
some of the startup duties previously done by crt0.o.
See “The crt0.o Startup File” on page 43, and crt0(3) manual page for
more information.
