Thanks for the reply.
If indeed it should be invoked with --config-new_macho=no, would it
be possible to auto-detect it? (while still allowing override)
With commit 62096265, '--config-new_macho=no' does not seem to make
a difference, and "hello-exe" still fails the same, starting with:
------------ hello-exe ------------
dyld: REBASE_OPCODE_SET_SEGMENT_AND_OFFSET_ULEB has segment 4 which is not a
writable segment (__LINKEDIT) in /Users/avih/dev/tcc/tcc.upstream/tests/./hello
/bin/sh: line 1: 58643 Abort trap: 6 ./hello
With current mob (4dc4e93), '--config-new_macho=no' does make
a difference, where now "hello-exe", "hello-run", and "libtest" do
pass, and "libtest_mt" passes some tests and then fails:

While this does not seem like a load issue anymore, I'm still
attaching the full output of configure && make && make test,
as well as of 'otool -l ./tcc' with current mob (4dc4e93).
