This is not correct.
The purpose of this code is to create a symbolic link named according
to 'ARCH_LIB_DIR' inside DESTDIR and DESTDIR/usr.
It is not the purpose to create a symbolic link called 'lib' inside a
directory DESTDIR/ARCH_LIB_DIR.
The change you made is creating a _directory_ ARCH_LIB_DIR while it
should be a _symbolic link_.
Could you please clarify what is the value of ARCH_LIB_DIR in your case?
And could you clarify which part of the path is missing?
'/.../host/riscv64-buildroot-linux-gnu/sysroot/lib64/lp64' ?
I assume that the 'lib64' part is missing?
Finally, please provide a defconfig that allows to reproduce and test
this problem.
Thanks,
Thomas
