Actually, you've just uncovered a bug in libtool. `-z defs' is the
appropriate -no-undefined flag, even though -z text would get a very
similar behavior, but for the wrong reasons. The latter forces an
error in case any relocation remains in a read-only section. So, -z
text wouldn't have caught a non-const pointer initialized to some
variable external to a shared library, whereas -z defs does. I've
checked that it's documented in Solaris 2.5 linker man-pages. I don't
know how far back that goes, though.
-z text is implicitly used by GCC when creating shared libraries,
unless -mimpure-text is given at compile time. That's probably one of
the reasons why we don't use GCC for linking on Solaris. We probably
could, if GCC supports -mimpure-text. When not using GCC, we can
probably just use the compiler.

This is certainly The Right Thing (TM) to do.

Just because GNU ld disregards `-z text', instead of properly
implementing it. As soon as it is fixed, this would no longer work.
