description:
postfix: enable lint again

Since init.c 1.229 from 2021-12-22, lint correctly parses and interprets
initializers with omitted braces, which are allowed by the C standards
but not recommended.

The warnings about empty declarations at file scope are suppressed
precisely.

Lint2 handles the generated .ln files fine in my local builds, I suspect
some truncated files as the cause for the unspecific "is broken" from
the comment.

-# For now, don't lint:
-# 1. postfix uses 'struct { const char *name; int value } foo[] =
-#    { "n1", v1, "n2, v2", 0 };' and this is broken (should be fixed in lint)
-# 2. uses macros with extra ; (macros should be fixed)
-# 3. lint2 is broken (should be fixed in lint2)
-# 4. use use MKLINT:=no since this might have been included too late.
