Doing up some housekeeping around the used CFLAGS. To be more generic put the default declaration for additional warning CFLAGS into configure.ac and clean up the Makefile.am's. There are the default CFLAGS variable that is a global variable if not re adjusted inside the different targets. The second variable for CFLAGS is the AM_CFLAGS definition that is used inside a Makefile as a global variable. There is also the possibility to graduate the CFLAGS for a single target. But currently there are nothing more than one target within each Makefile so we can set for now the target specific CFLAGS to the AM_CFLAGS. A new variable called WARNING_CFLAGS is inside the configure.ac created, this variable holds all the warnings flags inside. The Makefile.am's are taking the values and is setting the variable AM_CFLAGS which is used in the target specific CFLAGS. Also the options 'DWITH_POSIX' and 'D_GNU_SOURCE' are now appended to the CFLAGS if the configure script is detecting a *-[uc]linux* system.
