This is what is intended. It changes the compiler call to acknowledge the
settings rpm-packaging expects it to acknowledge.

It has the same effect as
make CC=%{__cc} CFLAGS="${RPM_OPT_FLAGS} -include /usr/include/errno.h"
would have with ordinary Makefiles.

Unfortunately DJB's build-system is "special" and doesn't allow overriding
settings from the environment, therefore one has to resort to hardcoding
settings (which is what this sed call does).

RPM_OPT_FLAGS is an rpm internal variable. It contains the CFLAGS all packages
are supposed to compile with.
