I'm still getting the same compile errors. It is because of multiple virtual/libc providers. The preferred provider variable gets set in the csl recipes, but it seems to be getting ignored for some reason. 

Have you tried to build with a recent version of the yocto master branch? Perhaps you too might encounter the same errors now.

My local.conf file is set as follows:

# Set the toolchain mode to external Xilinx toolchain pre-compiled binary.
TCMODE = "external-csl"
CSL_TARGET_SYS_microblazeel = "microblazeel-unknown-linux-gnu"
EXTERNAL_TOOLCHAIN = "/tool/xilinx/gnu/microblazeel-unknown-linux-gnu"
EXTERNAL_TOOLCHAIN_SYSROOT = "/tool/xilinx/gnu/microblazeel-unknown-linux-gnu/libc"
#NO32LIBS = "0"
