I have added new source: elf/tst-dlopen-aout-helper.c, and modified
elf/Makefile like so:

This produces

make[1]: Leaving directory `/glibc/elf'
make: *** No rule to make target `/build/elf/tst-dlopen-aout-helper',
needed by `/build/elf/tst-dlopen-aout.out'.  Stop.

If I comment in this line:

  $(objpfx)tst-dlopen-aout-helper: tst-dlopen-aout-helper.c

then there is no make error (but no tst-dlopen-aout-helper is linked either).

I am utterly failing to understand why implicit rules aren't kicking
in, or what I need to do to get tst-dlopen-aout-helper built.
