Original GitHub issue: https://github.com/netblue30/firejail/issues/3661

When compiling from source on Ubuntu 20.04, compilation fails with the following error unless gawk is installed (it isn't by default), even without enabling apparmor (see 01cdce7435). I'm not sure if this is a bug, expected behavior that needs documenting, or something that is documented and I just haven't seen it.

gawk is a new build dependency required for pre-processing manpages. It is not related to AppArmor.

Maybe we should check for gawk during configure?

Edit: though it should not be needed when building with --disable-man.

I think --disable-man is an edge case, so we'd probably better check for gawk.

I added the check for gawk only when manpages are also built (i.e. they are not disabled via --disable-man).
