[PATCH] m4_defn: avoid compiler warning

[Eric Blake]

argc is an int, therefore by definition, it is <= INT_MAX.

* src/builtin.c (m4_defn): Nuke redundant condition.

Signed-off-by: Eric Blake <address@hidden>

The redundant condition was part of an assert added in commit
1029ee26 to silence one gcc warning; now it provoked another
warning.  Oh well.
