Description

@tripzero

This is triggered during building intel-compute-runtime:master on:

[ 19%] Generating ../../../bin/built_ins/x64/gen8/aux_translation_Gen8core.spv, ../../../bin/built_ins/x64/gen8/aux_translation_Gen8core.bin, ../../../bin/built_ins/x64/gen8/aux_translation_Gen8core.cpp, ../../../bin/built_ins/x64/gen8/aux_translation_Gen8core.gen

failed trying to load symbol _igc_bif_BC_122_size 
Error loading the Generic builtin resource
Build failed with error code: -11

(the 'failed trying to load symbol' output is debug that I added to IGC/AdaptorOCL/OCL/LoadBuffer.cpp)

Running with LD_DEBUG=libs I see:
