Usually configure of bison checks for alloca and makes the proper
compile checks.  My guess is that either bison automatically uses -lucb
on its configure checks, or you got a bison precompile binary where
someone used -lucb.  I don't think bison requires it, but your's does.
Alloca can not easily be simulated.

NAME
     alloca - memory allocator

SYNOPSIS
     #include <stdlib.h>

     void *
     alloca(size_t size);

DESCRIPTION
     The alloca() function allocates size bytes of space in the stack
frame of
     the caller.  This temporary space is automatically freed on return.

RETURN VALUES
     The alloca() function returns a pointer to the beginning of the
allocated
     space.  If the allocation failed, a NULL pointer is returned.

SEE ALSO
     brk(2),  pagesize(2) calloc(3),  malloc(3),  realloc(3),
