	 *
	 * The ELF_C_GROUP field identifies a capabilities symbol.  Lead
	 * capability symbols, and lead capability aliases are identified by
	 * a CAPINFO_SUNW_GLOB group identifier.  For family members, the
	 * ELF_C_GROUP provides an index to the associate capabilities group
	 * (i.e, an index into the SUNW_cap section that defines a group).
	 *
	 * For relocatable objects, the ELF_C_SYM field identifies the lead
	 * capability symbol.  For the lead symbol itself, the .SUNW_capinfo
	 * index is the same as the ELF_C_SYM value.  For lead alias symbols,
	 * the .SUNW_capinfo index differs from the ELF_C_SYM value.  This
	 * differentiation of CAPINFO_SUNW_GLOB symbols allows ld(1) to
	 * identify, and propagate lead alias symbols.  For example, the lead
	 * capability symbol memcpy() would have the ELF_C_SYM for memcpy(),
	 * and the lead alias _memcpy() would also have the ELF_C_SYM for
	 * memcpy().
	 *
	 * For dynamic objects, both a lead capability symbol, and alias symbol
	 * would have a ELF_C_SYM value that represents the same capability
	 * chain index.  The capability chain allows ld.so.1 to traverse a
	 * family chain for a given lead symbol, and select the most appropriate
	 * family member.  The .SUNW_capchain array contains a series of symbol
	 * indexes for each family member:
	 *
	 *    chaincap[n]  chaincap[n + 1]  chaincap[n + 2]  chaincap[n + x]
	 *	foo() ndx    foo%x() ndx	foo%y() ndx	0
	 *
	 * For family members, the ELF_C_SYM value associates the capability
	 * members with their family lead symbol.  This association, although
	 * unused within a dynamic object, allows ld(1) to identify, and
	 * propagate family members when processing relocatable objects.
