Packages use 'aarch64-poky-linux-gcc -print-multi-os-directory' to get
the value of install directory. The value is set by MULTILIB_OSDIRNAMES
and default is '/lib64'. And the dynamic linker ld-linux-aarch64.so.1
from package eglibc is installed to /lib64.
But the default dynamic linker defined in gcc/config/aarch64/aarch64-linux.h
is:
MULTILIB_OSDIRNAMES = .=../lib64$(call
if_multiarch,:aarch64$(AARCH_BE)-linux-gnu)
Then cause all the ELF files fail to launch because fail to find the
linker and libraries.
Redefine default library install directory to /lib to fix this issue.
