commit 2ebfbef8d480d89ba11b9ca8f8adfb4340702a52
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>

arm: Implement memchr ifunc selection in C
This patch refactor ARM memchr ifunc selector to a C implementation.
No functional change is expected, including ifunc resolution rules.
It also reorganize the ifunc options code:
1. The memchr_impl.S is renamed to memchr_neon.S and multiple
compilation options (which route to armv6t2/memchr one) is
removed. The code to build if __ARM_NEON__ is defined is
also simplified.
2. A memchr_noneon is added (which as build along previous ifunc
resolution) and includes the armv6t2 direct.
3. Same as 2. for loader object.
Checked on armv7-linux-gnueabihf and with a build for arm-linux-gnueabi,
arm-linux-gnueabihf with and without multiarch support and with both
GCC 7.1 and GCC mainline.
* sysdeps/arm/armv7/multiarch/Makefile [$(subdir) = string]
(sysdeps_routines): Add memchr_noneon.
* sysdeps/arm/armv7/multiarch/ifunc-memchr.h: New file.

commit 7a205be997c8f08bcf238cd6fbc29d30ac3645e3

arm: Implement memcpy ifunc selection in C
This patch refactor ARM memcpy ifunc selector to a C implementation.
No functional change is expected, including ifunc resolution rules.
To avoid build issues with mainline GCC which set no default gnu
indirect function support for ARM (--enable-gnu-indirect-function)
two fixes are added:
1. The new macro arm_libc_ifunc_hidden_def is redefined using
direct asm assembly directives instead of function attributes.
This avoid the incompatbile types for a symbol and its alias.
2. A new macro NO_MEM_INTERAL_SYM_HACKS is added on symbol-hacks
and defined on arm ifunc objects. It avoids the symbol
definition loop because compiler might emit the hacks for first
fix before the ifunc function definition itself.
Checked on armv7-linux-gnueabihf and with a build for arm-linux-gnueabi,
arm-linux-gnueabihf with and without multiarch support and with both
GCC 7.1 and GCC mainline.

Add build-many-glibcs.py arm-linux-gnueabihf-v7{-disable-multiarch}
This patch adds two extra configuration for arm-linux-gnueabihf to
cover for multiarch support:
1. arm-linux-gnueabihf-v7a: enables multiarch support by using
-march=armv7a.
2. Same as 1. but with --disable-multiarch.
Check with build-many-glibcs.py for both options.
* scripts/build-many-glibcs.py (Context.add_all_configs):
Add arm-linux-gnueabihf multiarch extra_glibcs.

sparc: Implement memcpy/mempcpy ifunc selection in C
This patch refactor the SPARC64 ifunc selector to a C implementation.
The x86_64 implementation is used as default, which resulted in common
definitions (ifunc-init.h) used on both architectures. No functional
change is expected, including ifunc resolution rules.
Checked on sparc64-linux-gnu, sparcv9-linux-gnu and x86_64-linux-gnu.

commit 58ee535947f5b0a8dad0f2fe7984570ce06db61b
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Tue Oct 10 11:12:50 2017 -0300
Avoid build multiarch if compiler warns about mismatched alias
GCC 8 emits an warning for alias for functions with incompatible types
and it is used extensivelly for ifunc resolvers implementations in C
(for instance on weak_alias with the internal symbol name to the
external one or with the libc_hidden_def to set ifunc for internal
usage).
This breaks the build when the ifunc resolver is not defined using
gcc attribute extensions (HAVE_GCC_IFUNC being 0). Although for
all currently architectures that have multiarch support this compiler
options is enabled for default, there is still the option where the
user might try build glibc with a compiler without support for such
extension. In this case this patch just disable the multiarch folder
in sysdeps selections.
GCC 7 and before still builds IFUNCs regardless of compiler support
(although for the lack of attribute support debug information would
be optimal).
The patch also fixes the default value of the multiarch support in
configure.ac (the correct value which is tested later in the script
assumer 'yes' instead of 'default').
Checked with a build on multiarch support architectures (aarch64,a
arm, sparc, s390, powerpc, x86_64, i386) with multiarch enable
and disable and with GCC 7 and GCC 8.
