[PATCH] Makeconfig: Do not sort and deduplicate +cflags [BZ # 17248]

[Florian Weimer]

The original intent behind this is unclear.  It interferes with flags
that has to be ordered in a particular way.

This change does not introduce any changes in the built binaries on
x86-64, and build-many-glibcs.py shows no regressions, either.  (I did
not compare all object files, though.)
