(AC_SEARCH_LIBS): Remove file/macro, now that

this replacement is no longer needed.  Besides, this macro has
no effect with autoconf-2.58, since its `undefine' is not honored.

-dnl A replacement for autoconf's macro by the same name.  This version
-dnl uses `ac_lib' rather than `i' for the loop variable, but more importantly
-dnl moves the ACTION-IF-FOUND ([$]3) into the inner `if'-block so that it is
-dnl run only if one of the listed libraries ends up being used (and not in
-dnl the `none required' case.
-dnl I hope it's only temporary while we wait for that version to be fixed.
