Yes. Those rel.text sections do hold relocations. But the .o files are
not compiled with -fPIC. Without -Bsymbolic, linker will create/copy
those .rel.text sections in the resulting DSO. With -Bsymbolic, those
.rel.text sections seem to be removed. The Solaris/x86 linker generates
the .rel.text section with and without -Bsymbolic. I will check why
those .rel.text sections are removed.
