Get rid of all the duplicated settings of AM_CFLAGS in the makefiles
for the various core modules and use a single global setting so that
the flags are actually consistent everywhere.

Also get rid of most the USE_PIE blocks in the makefiles by having
configure pass expand a variable in the new global AM_CFLAGS to one
of "-fpie" or "" depending on whether PIE is in use.
