Makefile: improve dependency generation
Makefile target generation would always be included for any makefile target that was not clean. Only care to include the '.deps' directory when building cgit, rather than generating and including dependencies when calling other makefile targets. Heavily borrowed from git's Makefile, but without definitions to test for the compiler's header dependency feature. Previous Makefile implementation never checked for this compiler feature anyway. - Removed makecmdgoal 'clean' check - Grouped like .PHONY target definitions - Place build dependency targets under .SUFFIXES - Re-arranged location of library inclusion definitions - Use google code mirror instead of github Signed-off-by: Jamie Couture <jamie.couture@gmail.com> Signed-off-by: Jason A.
