The patch is straighforward:
- The sparc32 v8 implementations are moved as the generic ones.
- A configure test is added to check for either __sparc_v8__ or
__sparc_v9__.
- The triple names are simplified and sparc implies sparcv8.
The idea is to keep support on sparcv8 architectures that does support
CAS instructions, such as LEON3/LEON4.
Checked on a sparcv9-linux-gnu and sparc64-linux-gnu.

While working on another patch I noticed that (a)
sysdeps/sparc/sparc32/Makefile is the only place with special
realclean settings, apart from po/, and (b) the generated files with a
rule in that Makefile to generate them (using m4) had been patched
manually so no longer corresponded with the output of the generator -
so if the timestamps were wrong, a build would result in changes to
the files in the source directory. (They also didn't correspond
because of changes in make 3.81 to how make handles whitespace at the
start of a line in a sequence of backslash-newline continuation lines
within a recipe.)
This patch fixes the generation and output files to match. The issue
with make and whitespace at start of continuation lines is fixed by
putting those newlines outside of arguments to echo, so the number of
spaces in the argument matches the number in the existing generated
files. Then divrem.m4 is changed to avoid generating whitespace-only
lines (my fix to the outputs from 2013; this fix to the generator also
changes the indentation of a label in the output files) and to
generate an alias in udiv.S (Adhemerval's fix from March).
build-many-glibcs.py doesn't have a non-v9 SPARC configuration,
because non-v9 32-bit SPARC didn't build when I set up
build-many-glibcs.py but sparcv9 did build. Whether or not non-v9
32-bit SPARC now builds (or indeed whether or not support for it is
obsolete), I tested by removing the sparcv8 and sparcv9 versions of
the four files in question, so forcing the generated files to be built
and used, and the compilation parts of the glibc testsuite passed.
* sysdeps/sparc/sparc32/Makefile
($(divrem:%=$(sysdep_dir)/sparc/sparc32/%.S)): Do not include
start-of-line whitespace in argument of echo.
* sysdeps/sparc/sparc32/divrem.m4: Avoid generating lines starting
with whitespace. Generate __wrap_.udiv alias.
* sysdeps/sparc/sparc32/rem.S: Regenerated.
* sysdeps/sparc/sparc32/sdiv.S: Likewise.
* sysdeps/sparc/sparc32/udiv.S: Likewise.
* sysdeps/sparc/sparc32/urem.S: Likewise.

Sparc64 merge:
* configure.in: Change up subdirectories, rename sparc8->sparcv8.
* csu/Makefile: Nuke need-nopic-initfini bits. The problem was
that sparc64 ld did not recognize pic relocs at all.
* elf/dl-deps.c: Include <string.h>.
* elf/do-rel.h (elf_dynamic_do_rel): Take reloc address and size
directly instead of the DT names to get them from.
* elf/dynamic-link.h (_ELF_DYNAMIC_DO_RELOC): New macro distilled
from ELF_DYNAMIC_DO_REL{,A}. Define a second version that accounts
for the possibility that DT_RELA and DT_JMPPLT overlap, as such is
the case on the Sparc.
* elf/elf.h: Stub out Elf64_Ver*, and make them the same as the
Elf32_Ver* bits. The linker does not even know to differentiate
between the word sizes. Someone should examine this and figure
out what the proper sizes of things should be for 64-bit hosts
before the sparc64 libraries are distributed.
* shlib-versions: Rename sparc64 ld.so to not conflict with sparc32
on the same machine.
Move old sysdeps/sparc contents to sysdeps/sparc/sparc32,
rename sparc8 subdir to sparcv8, move sysdeps/sparc64 content to
sysdeps/sparc/sparc64. Same for sysdeps/unix/sysv/linux/sparc.

the later does not exist when running ld.so directly.

examples.
