650ba77ad5 crypt: Fix badsalttest test (Bug 22765)
The value of 'cd.initialized' is left uninitialized before the
first invocation of 'crypt_r ()' in this test despite the fact
that it should be set to zero according to the API.

RISC-V: Build Infastructure
This patch lays out the top-level orginazition of the RISC-V port.  It
contains all the Implies files as well as various other fragments of
build infastructure for the RISC-V port.  This contains the only change
to a shared file: config.h.in.

RISC-V is a family of base ISAs with optional extensions.  The base ISAs
are RV32I and RV64I, which are 32-bit and 64-bit integer-only ISAs, but
this port currently only supports RV64I based systems.  Support for
RISC-V lives in in sysdeps/riscv.  In addition to these ISAs, our glibc
port supports most of the currently-defined extensions: the A extension
for atomics, the M extension for multiplication, the C extension for
compressed instructions, and the F/D extensions for single/double
precision IEEE floating-point.  Most of these extensions are handled by
GCC, but glibc defines various floating-point wrappers and emulation
routines as well as some atomic wrappers.

We support running glibc-based programs on Linux, the support for which
lives in sysdeps/unix/sysv/linux/riscv.

RISC-V: Hard Float Support
This patch contains hardware floating-point support for the RISC-V ISA.
While we currently only support hard-float systems with both the F and D
extensions, I've left the F-specific code split out into seperate
folders in order to ease adding support for F-only and RV32I-based
systems in the future.  I gave this a quick once-over and believe I've
removed all the code that implements RV32IF, RV32IFD, and RV64IF
targets.

RISC-V: Thread-Local Storage Support
This patch implements TLS support for RISC-V.  We support all four
standard TLS addressing modes (LE, IE, LD, and GD) when running on
Linux via NPTL.  There is a draft psABI document that defines our TLS
ABI here

RISC-V: ABI Implementation
This patch contains code that needs to directly know about the RISC-V
ABI, which is specified in a work-in-progress psABI document:

  https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md

This is meant to contain all the RISC-V code that needs to explicitly
name registers or manage in-memory structure layout.  This does not
contain any of the Linux-specific code.

Add documentation for __riscv_flush_icache
This function is used by GCC to enforce ordering between data writes and
instruction fetches, and while we'd prefer that users rely on the GCC
intrinsic when possible this is user visible in case that's not
possible.

sysdeps/init_array: Add PREINIT_FUNCTION to crti.S
The RISC-V port contains a crti.S that simply contains a link to
PREINIT_FUNCTION (when defined).  As this should be entirely generic,
Joseph Myers suggested that we update the generic init_array version to
contain this.  Since RISC-V is the only user of init_array this won't
break any existing ports.

e3aa6999d7 Make build-many-glibcs.py clean git source directories.
With the git checkouts of Hurd components in build-many-glibcs.py
involving running autoreconf, there's a risk that generated files
could be left behind by an old autoreconf run (if an old version of
the sources generates those files in the source directory but a new
version does not).

This patch avoids that by using git clean -dxfq when updating git
checkouts.  In this patch, that's conditional on --replace-sources, to
avoid removing any local not-checked-in files someone may have in
their checkout unless the option has been specifically passed that
says it's OK to blow old checkouts away, complete with any local
changes to them.

	* scripts/build-many-glibcs.py (Context.git_checkout): Use git
	clean -dxfq for git updates when replacing sources.

088de7d009 Clean up build-many-glibcs.py libcilkrts disabling.
The disabling of libcilkrts in build-many-glibcs.py has some
peculiarities.  It's only for the final GCC build, not the initial
bootstrap one, whereas normally anything disabled for the final build
should be disabled for the bootstrap one as well.  And it's only for
Hurd, when it's more natural by analogy with the libsanitizer
disabling to disable this library unconditionally, not only for
targets where it's known to break.  This patch cleans up that
disabling accordingly, adding a comment so it's obvious it can be
removed once GCC 7 is too old to build glibc.

	* scripts/build-many-glibcs.py (Config.build_gcc): Use
	--disable-libcilkrts unconditionally, not just for the final GCC
	build for Hurd.
