After #90 , it no more needs to run the qemu on the ARM32 host. The time of the stage-2 build has decreased from ~25s to 4s.
The uftrace
needs the debug symbols (built with GCC "-g" and "-finstrument-functions" flags) to trace the executable file. We can only use it in the stage-1 build, instead, we can use perf
to identify the slowdowns in the stage-2 build.
