No need to send any more files. I see the problem:
The build system type is determined as x86_64-apple-darwin20.4.0
, not as aarch64-apple-darwin20.4.0
as it should be on an M1 Mac. That will cause configure
to enable the JIT.
So it seems that on your M1 Mac homebrew is running under Rosetta emulation (emulating an Intel Mac), at least when the configure
script is run. I don’t know why that is happening. Did the first versions of homebrew for M1 Macs run under emulation and you are still using that version? With my recently installed homebrew, the configure
script correctly determines the build type to be aarch64-apple-darwin20.4.0
