ld: sprintf sanitizer null destination pointer
* configure.ac (stpcpy): AC_CHECK_DECLS.
* sysdep.h (stpcpy): Add fallback declaraion.
* config.in: Regenerate.
* configure: Regenerate.
* emultempl/pe.em (open_dynamic_archive): Use
stpcpy rather than sprintf plus strlen.
* emultempl/pep.em (open_dynamic_archive): Likewise.
* emultempl/xtensaelf.em (elf_xtensa_before_allocation): Use
auto rather than malloc'd buffer. Use sprintf count.
* ldelf.c (ldelf_search_needed): Use memcpy in place of sprintf.
* pe-dll.c (pe_process_import_defs): Use string already formed
for alias match rather than recreating.
