Andreas Fritiofson ef4c139ce2 configure: Don't set user variables ...

CFLAGS is a user variable and shouldn't be set in either
configure.ac or Makefile.am because that makes it impossible to
override compiler flags at configure or make time.

AC_SUBST the default warning flags into AM_CFLAGS instead, which
is emitted before CFLAGS on the compiler command line.

Do the same thing with a mingw-specific flag as well.
