Hi Tom,

This seems to cause issues when building gdbserver as part of a larger
Canadian Cross ARM/AArch64 build. ar ends up confused having seemingly lost
the expected flags:

	  ./regex.o ./cplus-dem.o ./cp-demangle.o ./md5.o ./sha1.o ./alloca.o ./argv.o ./choose-temp.o ./concat.o ./cp-demint.o ./crc32.o ./dwarfnames.o ./dyn-string.o ./fdmatch.o ./fibheap.o ./filename_cmp.o ./floatformat.o ./fnmatch.o ./fopen_unlocked.o ./getopt.o ./getopt1.o ./getpwd.o ./getruntime.o ./hashtab.o ./hex.o ./lbasename.o ./lrealpath.o ./make-relative-prefix.o ./make-temp-file.o ./objalloc.o ./obstack.o ./partition.o ./pexecute.o ./physmem.o ./pex-common.o ./pex-one.o ./pex-unix.o ./safe-ctype.o ./simple-object.o ./simple-object-coff.o ./simple-object-elf.o ./simple-object-mach-o.o ./simple-object-xcoff.o ./sort.o ./spaces.o ./splay-tree.o ./stack-limit.o ./strerror.o ./strsignal.o ./timeval-utils.o ./unlink-if-ordinary.o ./xatexit.o ./xexit.o ./xmalloc.o ./xmemdup.o ./xstrdup.o ./xstrerror.o ./xstrndup.o  ./setproctitle.o

       ar -M [<mri-script]

----

The small patch below (from your initial patch series) gets the build
going again, but looking back at the discussion, I see this was
controversial and was dropped before the final commit.

My knowledge of the build system is minimal, but I'm happy to test any
proposed patches.

Thanks,
James Greenhalgh
