swiftc(1) requires every -D option to be prefixed with -Xcc, which is not easy to achieve using autoconf. Now instead of setting configuration macros like HAVE_LSEEK64 on the command line using -D, they are defined in config.h, which is generated by ./configure, ignored by Git, and included by all headers and source files that use any configuration macro. The dependency on Makefile has been replaced with a dependency on Makefile.in and config.h, which helps avoid some redundant full recompiles after running ./configure, because the configure script does not overwrit config.h if its content does not change.
