DESCRIPTION
match PATTERN. (If we've already read a shared object's symbol
info, leave it alone.) If PATTERN is zero, read them all.
+ If READSYMS is 0, defer reading symbolic information until later
+ but still do any needed low level processing.

FROM_TTY and TARGET are as described for update_solib_list, above. */
