* sysdeps/unix/sysv/linux/arm/Versions (libc: GLIBC_PRIVATE): New set.
	* sysdeps/unix/sysv/linux/arm/nptl/Versions: File removed.

	* sysdeps/unix/sysv/linux/arm/Makefile
	[$(subdir) = rt] (librt-sysdep_routines, librt-shared-only-routines):
	Add rt-aeabi_unwind_cpp_pr1.
	[$(subdir) = nptl] (librt-sysdep_routines, librt-shared-only-routines):
	Add nptl-aeabi_unwind_cpp_pr1.
	[$(subdir) = nptl] (tests): Filter out tst-cleanupx4.
	* sysdeps/unix/sysv/linux/arm/nptl/Makefile: File removed.
	* sysdeps/unix/sysv/linux/arm/nptl/rt-aeabi_unwind_cpp_pr1.c: Move ...
	* sysdeps/unix/sysv/linux/arm/rt-aeabi_unwind_cpp_pr1.c: ... here.
	* sysdeps/unix/sysv/linux/arm/nptl/nptl-aeabi_unwind_cpp_pr1.c: Move ...
	* sysdeps/unix/sysv/linux/arm/nptl-aeabi_unwind_cpp_pr1.c: ... here.

	* sysdeps/unix/sysv/linux/arm/configure.ac: Force -fexceptions here.
	* sysdeps/unix/sysv/linux/arm/configure: Regenerated.
	* sysdeps/unix/sysv/linux/arm/nptl/configure.ac: File removed.
