 *    -z dtrace=symbol		assigns symbol to PT_SUNWDTRACE segment,

 *
 *    -z noreloc		suppress relocation processing.  This provides
 *				a mechanism for validating kernel module symbol
 *				resolution that would normally incur fatal

 *
 *    -z rtldinfo=symbol	assigns symbol to SUNW_RTLDINF dynamic tag,
 *				providing pre-initialization specific routines
 *				for TLS initialization.
 *
 *    -z nointerp		suppress the addition of an interpreter
 *				section.  This is used to generate the kernel,
 *				but makes no sense to be used by anyone else.
