[PATCH] maint: avoid a new syntax-check failure (exempt mbcel.h from GPL version check)

[Jim Meyering]

make syntax-check was failing, so I pushed this, at least temporarily.
With that, I see that the ignore-case test has two failures.
I'm guessing Paul's working on that.

* cfg.mk (exclude_file_name_regexp--sc_GPL_version): Exempt mbcel.h,
which is GPL-2.1. Remove this exemption if/when mbcel.h moves to gnulib.
