cover postinst and clang fixes

This pull fixes boost with clang
other fixes are needed for risc-v to enable offline locale and postint generation, especially after
https://patchwork.openembedded.org/patch/154363/

Now we can boot qemuriscv64 quite fast

The following changes since commit 0d69f86e50e57afe893dade095c1dbd3d05c3b0f:

libsdl2: Fix left rotated display for RaspPi/VC4/GLES2 (2018-08-29 15:43:18 +0100)

are available in the Git repository at:

git://git.openembedded.org/openembedded-core-contrib kraj/pu-1
http://cgit.openembedded.org/openembedded-core-contrib/log/?h=kraj/pu-1

Khem Raj (4):
boost: Fix invalid const in atomic builtins
libc-package: Add risc-v specific options to cross-localedef
invocation
sysklogd: Use update-alternatives
glibc-locale: Enable riscv64 and riscv32 in BINARY_LOCALE_ARCHES
supported architectures

+Date: Tue, 17 Jul 2018 12:37:29 +0300
+Subject: [PATCH] Removed clang-specific branch for x86 DCAS-based loads.
+
+The storage to load from is const-qualified and DCAS via compiler intrinsics
+require an unqualified pointer. Use asm implementation instead, which should be
+as efficient as intrinsics, if not better, in this case.
+
+Fixes https://github.com/boostorg/atomic/issues/15.
+
+Upstream-Status: Backport [https://github.com/boostorg/atomic/commit/6e14ca24dab50ad4c1fa8c27c7dd6f1cb791b534]

PATCH 3/4 sysklogd: Use update-alternatives

In reply to Khem Raj

busybox also provides klogd and syslogd, this change makes it coexist peacefully. Currently rootfs fails in situations where both of them are providing these binaries and busybox postinsts fail

update-alternatives: Error: not linking /mnt/a/oe/build/tmp/work/qemuriscv64-bec-linux/core-image-full-cmdline/1.0-r0/rootfs/sbin/klogd to /bin/busybox.nosuid since /mnt/a/oe/build/tmp/work/qemuriscv64-bec-linux/core-image-full-cmdline/1.0-r0/rootfs/sbin/klogd exists and is not a link

PATCH 4/4 glibc-locale: Enable riscv64 and riscv32 in BINARY_LOCALE_ARCHES supported architectures

In reply to Khem Raj

This support is there using cross-localedef but was not enabled, this caused the post-install for locales to be emitted which delays the boot significantly.

emitted postints for locales contain exit 1 which is flagged now and was causing image generation to fail.
