Comment (by barracuda156):

 Replying to [comment:1 kencu]:

 So it looks like paths are correct and libs are passed to the linker, and
 `__Unwind_Resume` is here:
 {{{
 36-249:jemalloc-5.3.0 svacchanda$ nm -arch ppc -g
 /opt/local/libexec/gcc10-bootstrap/lib/libstdc++.6.dylib | grep _Unw
          U __Unwind_DeleteException
          U __Unwind_GetDataRelBase
          U __Unwind_GetIPInfo
          U __Unwind_GetLanguageSpecificData
          U __Unwind_GetRegionStart
          U __Unwind_GetTextRelBase
          U __Unwind_RaiseException
          U __Unwind_Resume
          U __Unwind_Resume_or_Rethrow
          U __Unwind_SetGR
          U __Unwind_SetIP
 }}}

 And here:
 {{{
 36-249:jemalloc-5.3.0 svacchanda$ nm -arch ppc -g
 /opt/local/libexec/gcc10-bootstrap/lib/libgcc_ehs.1.1.dylib | grep _Unw

 000037fc T __Unwind_SetGR
 000038ac T __Unwind_SetIP
 }}}

 The latter seems to be linked to `libgcc_s.1.dylib`:
 {{{

 I do not know what to do now :)
