35  *
36  *    -z dtrace=symbol		assigns symbol to PT_SUNWDTRACE segment,
37  *    				providing scratch area for dtrace processing.
38  *
39  *    -z noreloc		suppress relocation processing.  This provides
40  *				a mechanism for validating kernel module symbol
41  *				resolution that would normally incur fatal
42  *				relocation errors.
43  *
44  *    -z rtldinfo=symbol	assigns symbol to SUNW_RTLDINF dynamic tag,
45  *				providing pre-initialization specific routines
46  *				for TLS initialization.
47  *
48  *    -z nointerp		suppress the addition of an interpreter
49  *				section.  This is used to generate the kernel,
50  *				but makes no sense to be used by anyone else.
51  *
52  *    -z norelaxreloc		suppress the automatic addition of relaxed
53  *				relocations to GNU linkonce/COMDAT sections.
