Hi Than,
It turned out to be the problem of shell. By SHELL=/bin/sh I can build
gollvm in the right way, but I still failed on a compile error:

I checked the structure go_create_gogo_args (in gollvm/bridge/go-c.h) and
there really wasn't a field called debug_optimization there. Could I add
this field in go_create_gogo_args so I can let the build progress continue?
Thanks.
