Title:
  ld prints misleading errors about being unable to read symbols from
  .so files in /usr/lib

Status in “binutils” package in Ubuntu:
  Incomplete

Bug description:
  I was trying to build Brogue and encountered this error:

      mg at platonas:/tmp/brogue-1.5.2 $ make
      gcc -O3 -o bin/brogue src/brogue/Architect.o src/brogue/Combat.o src/brogue/Dijkstra.o src/brogue/Globals.o src/brogue/IO.o     src/brogue/Items.o src/brogue/Light.o src/brogue/Monsters.o src/brogue/Movement.o src/brogue/Recordings.o     src/brogue/RogueMain.o src/brogue/Random.o src/platform/main.o src/platform/platformdependent.o src/platform/curses-    platform.o src/platform/tcod-platform.o src/platform/term.o -L. -Lsrc/libtcod-1.5.1 -ltcod -lncurses -lm -Wl,-rpath,.
      /usr/bin/ld: src/platform/tcod-platform.o: undefined reference to symbol 'SDL_GetAppState'
      /usr/bin/ld: note: 'SDL_GetAppState' is defined in DSO /usr/lib/libSDL-1.2.so.0 so try adding it to the linker command line
      /usr/lib/libSDL-1.2.so.0: could not read symbols: Invalid operation
      collect2: ld returned 1 exit status
      make: *** [bin/brogue] Error 1

  The last message (about /usr/lib/libSDL) made me doubt the integrity
  of my system ("Invalid operation" while reading brings to mind disk
  failures).  Apparently it doesn't mean anything: libSDL is just fine,
  my disk is just fine, and all I need to do is edit the Makefile and
  add -lSDL in the proper place to get it to link.

  Can the misleading error message please be removed?
