[OE-core] [PATCH 2/2] libgcc: ensure gnueabi suffix is added when necessary

[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.
