/* For SVR4 shared libraries, each call to a library routine goes through
a small piece of trampoline code in the ".plt" section.
The horribly ugly wait_for_inferior() routine uses this macro to detect
when we have stepped into one of these fragments.
We do not use lookup_solib_trampoline_symbol_by_pc, because
we cannot always find the shared library trampoline symbols
(e.g. on Irix5). */
