mk: speed up notmuch detection

Use gcc instead of go to build a basic program and determine if notmuch
is available. Building a minimal go program takes more than 300ms on
a fast machine. A minimal C counterpart takes less than 100ms.

To avoid lag when doing bash completion, avoid running any shell
commands directly during make evaluation.

Rename check-notmuch.sh to goflags.sh and make that script print the
goflags directly.
