Fix #8321

Thanks! Just one minor autoconf output style issue.

Is only UCX 1.8.x bad? Or is it all versions <v1.9.0?

We checked, only v1.8.x is affected.

Looks like all those CI's are failing because they're using UCX 1.8. 😆

This is how it looks with e2231e6 and --with-ucx=/tmp/ucx-v1.8/install:

checking for MCA component common:ucx compile mode... dso
checking --with-ucx value... sanity check ok (/tmp/ucx-v1.8/install)

No --with-ucx, but just adding ucx-v1.8 to library/include paths:

@jsquyres your comments were applied, do we want to wait until CI is fixed?

[jsquyres]

I took the liberty of squashing both commits down into a single commit.

@yosefe You might want to update your .gitconfig for your new email address for future commits. 😄

[jsquyres]

@yosefe Can you PR this to v4.0.x and v4.1.x?

Thanks!
