1.8.0-rc1 still doesn't support Intel 1API

configure: error: Unsupported Intel compiler detected

Not sure if it will fix this issue, but @nmnobre has been looking into configure support for Intel compilers recently, see: libMesh/autoconf-submodule#17. Once that submodule update is merged into libmesh master, I can also cherry-pick it onto the release branch for the next release candidate.

[nmnobre]

Yes, this is definitely fixed. devel (and master) already has a preliminary fix that'll get you past that configure error, and libMesh/autoconf-submodule#17 further improves support with a slightly better choice for the optimisation flags.

[VictorEijkhout]

Meaning it's fixed post rc1? If so I'll wait for the official release.

[jwpeterson]

I'll comment here when rc2 is available for testing with this update.
