I can fix this via adding -Wl,-rpath=xxx into gcc command line when
compiling scripts/kconfig/mconf.  Is there any better solution?

A more general use case, say I want to develop a GTK application, so I
use pkg-config to get the compiler options.  But it appears that this
doesn't work on Guix because the RUN_PATH doesn't set in the built
binaries.  How to do that in Guix?
