Sure, but "taking advantage of system-specific features, but not
requiring them" is also a description of what optional check for
pkg-config in configure does.

Anyway, if you'd rather users should specify the system config on the
configure command line, it's obviously your choice.

[My _personal_ goal for writing a configure file is that it should work
without guidance on "common" systems.  Obviously this is sometimes
difficult and not worth it -- but pkg-config often makes it much
