Warnings: add AM_CFLAGS also for the psppire build

With the new setup the psppire and glade build honours the
AM_CFLAGS setup. This includes the Wextra warnings which
show some more warnings. The two checks which are disabled are

-Wno-sign-compare     : disabled also for core pspp
-Wno-unused-parameter : many callbacks result in unused parameters
