'make vdso_install' installs debug vdso files to /lib/modules/*/vdso/.
Only for the compat vdso on riscv, the installation destination differs;
compat_vdso.so.dbg is installed to /lib/module/*/compat_vdso/.
To follow the standard install destination and simplify the vdso_install
logic, change the install destination to standard /lib/modules/*/vdso/.

Couldn't changing this library install path break some existing
application? I mean it kind of breaks where the library is expected to
be right?

Do you have a particular library in mind?
RISV-V is the only architecture that installs a debug vdso
to a different location than the
standard lib/modules/*/vdso/.
I regard this as a fix.

You're probably right, I don't see why the search path would be
different on riscv, unless it was fixed in userspace but I think this is
the right thing to do, so:

Hello Palmer,
Ping x 3. Any chance for this to land during the MW?
It has been 4 months since the submission.

We do have some weirdness with multlib paths, but I don't think that's
related to the VDSO paths.
