Is libdl supported at all on riscv? In the new build system I excluded 
the libdl tests from the build for riscv. Do we need something like this:

diff --git a/testsuites/libtests/configure.ac 
b/testsuites/libtests/configure.ac
index 3b5462600d..fa07269c1a 100644

    bfin)

Plus a ticket to add libdl support for riscv?

I wonder why the BSP builder didn't surface this issue here.
