PATCH 1/2 cross-canadian/libgcc: fix aarch64's multilib SDK

From: Robert Yang <[email protected]>

The arm toolchain has a "-gnueabi" suffix, but aarch64 doesn't, this makes multilib sdk doesn't work, for example:

MACHINE = qemuarm64
require conf/multilib.conf
MULTILIBS = "multilib:lib32" DEFAULTTUNE_virtclass-multilib-lib32 = "armv7at-neon"

$ bitbake core-image-minimal -cpopulate_sdk

Then extract SDK, the environment-setup-armv7a-vfp-neon-pokymllib32-linux-gnueabi doesn't work since:
* The CC is arm-pokymllib32-linux-gnueabi-gcc
which doesn't exist, the patch for cross-canadian.bbclass fixes problem.
* Need aarch64-poky-linux/usr/lib/arm-poky-linux-linux-gnueabi which doesn't exist, the patch for libgcc-common.inc fixes the problem.

[YOCTO #8616]

PATCH 2/2 libgcc: ensure gnueabi suffix is added when necessary

In reply to Chen Qi

The '32' symlink in aarch64 multilib is broken. An example configuration to reproduce the bug is as follows.

MACHINE = qemuarm64
require conf/multilib.conf
MULTILIBS = "multilib:lib32" DEFAULTTUNE_virtclass-multilib-lib32 = "armv7at-neon"

Build and install SDK, then we would find the following symlink is broken.

./sysroots/aarch64-poky-linux/usr/lib64/aarch64-poky-linux/5.3.0/32

The patch fixes the above problem.

[YOCTO #8642]
