41  *				relocation errors.
42  *
43  *    -z rtldinfo=symbol	assigns symbol to SUNW_RTLDINF dynamic tag,
44  *				providing pre-initialization specific routines
45  *				for TLS initialization.
46  *
47  *    -z nointerp		suppress the addition of an interpreter
48  *				section.  This is used to generate the kernel,
49  *				but makes no sense to be used by anyone else.
50  *
51  *    -z norelaxreloc		suppress the automatic addition of relaxed
52  *				relocations to GNU linkonce/COMDAT sections.
53  *
