Hi,
I cloned the current version (as of a few hours ago) of sage from github and tried to build (didn't run config.) Ubuntu 17.04, Intel i7-7500U, etc. It quit around the openblas part.
Not quite sure how to parse the log---any advice appreciated. Happy to provide further details if needed.

Hi,
indeed, it's a problem with openblas' support of some newer Intel chips, see
A workaround is to do
$ OPENBLAS_CONFIGURE="TARGET=ATOM" make
(this tells openblas to configure assuming a low-end Intel chips commands only)
