   I was given some .o files with .rel.text sections and linker
   removes them when generating DSO with -Bsymbolic.

.rel.text section normally hold relocations.  The linker expects them
to do so.  Do these .rel.text sections hold relocations?  If they do,
then naturally the linker will remove them, just as it removes all
relocation sections.

The .rel.text sections which appear in the default linker scripts are
intended to handle newly created .rel.text section, for relocations
which must be copied into the shared library.
