Fix CFLAGS for non-GCC compilers.

* configure.in (CFLAGS): Always use -g like it was done before the
2010-03-30 change.
(REAL_CFLAGS): Use CFLAGS for non-GCC to get optimization flags.  (Bug#6538)

-dnl C_OPTIMIZE_SWITCH unused save for gcc, so why set it for non-gcc?
 dnl Note AC_PROG_CC sets CFLAGS to -g -O2 for gcc anyway.
