 *
 *    -z dtrace=symbol		assigns symbol to PT_SUNWDTRACE segment,
 *    				providing scratch area for dtrace processing.
 *
 *    -z noreloc		suppress relocation processing.  This provides
 *				a mechanism for validating kernel module symbol
 *				resolution that would normally incur fatal
 *				relocation errors.
 *
 *    -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.
 *
 *    -z norelaxreloc		suppress the automatic addition of relaxed
 *				relocations to GNU linkonce/COMDAT sections.
 *
 *    -z nosighandler		suppress the registration of the signal handler
 *				used to manage SIGBUS.
