building with --disable-shared fails

[Alexandre Oliva]

We attempt to compile elf/dl-caller.c without ever creating
gnu/lib-names.h, that it includes and whose macros it needs.  The
rules to create this file are conditional on --enable-shared, but the
compilation of dl-caller.c isn't.

I'm not sure what's the best way to fix this.  Suggestions?
