The module 'findprog-lgpl' is pretty broken, since it was introduced on
2008-09-02:
- It never produces any code.
- When used together with the module 'findprog', that module produces no code
either.
In both cases, a link error regarding the symbol 'find_in_path' results.
This patch fixes it.

findprog-lgpl: Fix link error (existing since 2008-09-02).
* modules/findprog-lgpl (Makefile.am): Arrange to compile
findprog-lgpl.c, not findprog.c.
* lib/findprog.c (find_in_path): Add LGPLed replacement code for
XNMALLOC.
