configure: Separate dependency flags from general CFLAGS

Before, there was an unfortunate interaction with 'make checkheaders':
Compiling a .h file would generate a .d dependency information file for
that .h file as a sideeffect of compilation. Unfortunately this would
clobber the .d files of the .c files with the same basename, resulting
in broken dependency information when running plain make.
