um... I have tried to reproduce it on a64fx machine. It looks it is failed with the big number of parallel tasks of ninja build. When I run the failed command manually, it is passed... If I reduce the number of the parallel tasks with ninja build like `ninja -j16`, the build is also passed... it could be memory allocation error from the bigger memory allocation than before...
The stage2 build and check-all are passed on Cortex-A72 machine...
To be safe, for now, I would like to disable `shouldMaximizeVectorBandwidth` for SVE...
Let me update this patch with it.
