Get the section-relative offset for the specified ELF symbol which is bound to
the specified section.  If the symbol has an absolute symbol value/offset this method
should return null.
<p>
For Harvard Architectures it may be necessary to adjust offset if section was mapped
to a non-default data space.
<p>
The default behavior is to return {@link ElfSymbol#getValue()} if {@link ElfHeader#isRelocatable()}
is true.

@param section ELF section header which is specified by the ELF symbol
@param sectionBase memory address where section has been loaded.  Could be within overlay
space if load conflict occured.
@param elfSymbol ELF symbol
@return section relative symbol offset or null if symbol value offset is absolute
