Running make with RECURSIVE_DEP_IS_ERROR=1 will cause a hard failure
when a recursive dependency is detected. This is useful to apply
stricter Ci tests, for example.

Instead of passing pkg-config location through a variable when building
qconf (make xconfig), prepend its parent directory to the PATH, as it is
being done for other conf targets.
Use a Makefile pattern rule to group all 'scripts/config/%onf'
(currently conf, mconf, qconf) targets in a single rule. Add -O2 to
CFLAGS when building them as well.
