This fixes an inconsequential objcopy memory leak. I'd normally ignore reports of leaks like this one, that are merely one block or fewer per section processed, since objcopy soon exits and frees all memory. However I thought it worth providing support for allocating memory on a bfd objalloc in objcopy and other utils. PR 29233 * bucomm.c (bfd_xalloc): New function. * bucomm.h (bfd_xalloc): Declare. * objcopy.c (copy_relocations_in_section): Use it to allocate array of reloc pointers. Rewrite code stripping relocs to do without extra memory allocation.
