Update all sourceware links to https. The website redirects everything to https anyway so let the web server do a bit less work. The only reference that remains unchanged is the one in the old ChangeLog, since it didn't seem worth changing it. * NEWS: Update sourceware link to https. * configure.ac: Likewise. * crypt/md5test-giant.c: Likewise. * dlfcn/bug-atexit1.c: Likewise. * dlfcn/bug-atexit2.c: Likewise. * localedata/README: Likewise. * malloc/tst-mallocfork.c: Likewise. * manual/install.texi: Likewise. * nptl/tst-pthread-getattr.c: Likewise. * stdio-common/tst-fgets.c: Likewise. * stdio-common/tst-fwrite.c: Likewise. * sunrpc/Makefile: Likewise. * sysdeps/arm/armv7/multiarch/memcpy_impl.S: Likewise. * wcsmbs/tst-mbrtowc2.c: Likewise. * configure: Regenerate. * INSTALL: Regenerate.
