Workaround a bug in GNU make when reloading generated makefiles The problem was discovered testing parallel builds. The configuration rules depend on generated pkg-config.mk files. However, experimentally, variables set in these files are not correctly reloaded in rules declared in other variables. Specifically, $(CFLAGS_PKGCONFIG) was not re-expanded after being modified, which led to configuration builds to lack the required flags, causing false configuration step failures. The flags are now explicitly listed using $(shell cat...), which is a little bit more expensive during the configuration step, but ensures that the flags are correctly seen. Note that at that stage, the dependency ensures that all the files were built correctly.
