Thanks, but I'd rather not go through the glibc regex implementation
looking for other instances of this problem; it will be a maintenance
and reliability hassle.

Instead, let's substitute a malloc that behaves compatibly with GNU
malloc.  I installed this change into gnulib, and I expect when this
patch trickles into sed, then sed will use the gnulib malloc
substitute on uClibc, and that will fix the problem there.

        * modules/regex (Depends-on): Add malloc, since the code
        assumes that !malloc(0) means failure.
