rules.mk: make PKG_CONFIG_DEPENDS properly track string values
The confvar macro is adjusted to not only consider if a variable has a value or not, but also the value itself. Instead of creating a string of 'y' and 'n' characters, all variable names and values are concatenated and hashed. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>
