/* Creating inferior hooks here has two purposes. First, if we reload
shared libraries then the address of solib breakpoint we've computed
previously might be no longer valid. For example, if we forgot to set
solib-absolute-prefix and are setting it right now, then the previous
breakpoint address is plain wrong. Second, installing solib hooks
also implicitly figures were ld.so is and loads symbols for it.
Absent this call, if we've just connected to a target and set
solib-absolute-prefix or solib-search-path, we'll lose all information
about ld.so. */
