"pkglint -e -Wall" says
WARN: Makefile:17: Permission [a] requested for USE_LANGUAGES, but only
[s] is allowed.
The available permissions are:
a append something using +=
d set a default value using ?=
s set a variable using :=, =, !=
p use a variable during preprocessing
u use a variable at runtime
A "?" means that it is not yet clear which permissions are allowed
and which aren't.

*** Please consider adding USE_LANGUAGES+=...

I do not understand what it says.
Are we supposed to explicitly list a C compiler as necessary or can we
rely on the pkgsrc guide (and the comment in compiler.mk) that
The default is "c"
