libgcc-common.inc: Fix broken symlinks for multilib SDK

This patch fixes broken "32" symlinks for multilib settings:

MACHINE = "qemuarm64"
require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "armv7a"

and

MACHINE = "qemux86-64"
require conf/multilib.conf
MULTILIBS = "multilib:libx32"
DEFAULTTUNE_virtclass-multilib-libx32 = "x86-64-x32"

[YOCTO#8642]
[YOCTO#10380]
