[OE-core] [PATCH 20/24] glibc-package: aarch64 enable symlink for ABI compliance

[Kai Kang]

From: Mark Hatle <mark.hatle at windriver.com>

aarch64 requires the ld.so to be present in /lib, even if the rest
of the libraries are installed into an alternative directory.

See: https://sourceware.org/glibc/wiki/ABIList
