[bug-gnulib] alloca and alloca-opt conflict

[Simon Josefsson]

The modules getdate and vasnprintf depend on alloca and alloca-opt,
respectively, which causes this:

Makefile:602: warning: overriding commands for target `alloca.h'
Makefile:595: warning: ignoring old commands for target `alloca.h'

The only difference between alloca and alloca-opt seem to be the
alloca.c file and the license.  How about this patch?

        * modules/alloca: Depend on alloca-opt, instead of duplicating it.
