build: allow non-standard variations of linker -l/-L flags This enables replacing the -l and -L flags used to specify the just-built libraries when linking the tools and shared libs with non-standard syntaxes. System library flags are already handled by the filtering mechanism in configure. Signed-off-by: Mans Rullgard <mans@mansr.com>

SKIPHEADERS += $(ARCH_HEADERS:%=$(ARCH)/%) $(SKIPHEADERS-)
SKIPHEADERS := $(SKIPHEADERS:%=$(SUBDIR)%)
build: change checkheaders to use regular build rules Many compilers need special flags to compile *.h files as regular source code, if they will do so at all. Rather than hoping all compilers will have such a flag and adding mappings for it, create wrapper .c files for test building single headers. This allows using the regular rule for compiling C files without the need for special flags, and it also provides proper dependency tracking for these objects.

Integrate lcov/gcov into Libav The gcov/lcov are a common toolchain for visualizing code coverage with the GNU/Toolchain. The documentation and implementation of this integration was heavily inspired from the blog entry by Mike Melanson: http://multimedia.cx/eggs/using-lcov-with-ffmpeg/
