Try these linker flags:
`-q'
`--emit-relocs'
Leave relocation sections and contents in fully linked
exececutables. Post link analysis and optimization tools may need
this information in order to perform correct modifications of
executables. This results in larger executables.
`-r'
`--relocateable'
Generate relocatable output--i.e., generate an output file that
can in turn serve as input to `ld'. This is often called "partial
linking". As a side effect, in environments that support standard
Unix magic numbers, this option also sets the output file's magic
number to `OMAGIC'. If this option is not specified, an absolute
file is produced. When linking C++ programs, this option _will
not_ resolve references to constructors; to do that, use `-Ur'.
When an input file does not have the same format as the output
file, partial linking is only supported if that input file does
not contain any relocations. Different output formats can have
further restrictions; for example some `a.out'-based formats do
not support partial linking with input files in other formats at
all.
This option does the same thing as `-i'.
