* Without this flag we only support one copy of the linker in a
* process because by default the linker will always try to
* initialize at one primary link map The copy of libc which is
* initialized on a primary link map will initialize global TLS
* data which can be shared with other copies of libc in the
* process. The problem is that if there is more than one copy
* of the linker, only one copy should link libc onto a primary
* link map, otherwise libc will attempt to re-initialize global
* TLS data. So when a copy of the linker is loaded with this
* flag set, it will not initialize any primary link maps since
* presumably another copy of the linker will do this.
*
* Note that this flag only allows multiple copies of the -same-
* -version- of the linker (and libc) to coexist. This approach
* will not work if we are trying to load different versions of
* the linker and libc into the same process. The reason for
* this is that the format of the global TLS data may not be
* the same for different versions of libc. In this case each
* different version of libc must have it's own primary link map
* and be able to maintain it's own TLS data. The only way this
* can be done is by carefully managing TLS pointers on transitions
* between code associated with each of the different linkers.
* Note that this is actually what is done for processes in lx
* branded zones. Although in the lx branded zone case, the
* other linker and libc are actually gld and glibc. But the
* same general TLS management mechanism used by the lx brand
* would apply to any attempts to run multiple versions of the
* solaris linker and libc in a single process.
