I tried to build Linux kernel by hand with Guix.  But run `make
menuconfig` failed.  I checked the menuconfig program, found some
library couldn't be found.

$ ldd scripts/kconfig/mconf
	linux-vdso.so.1 (0x00007ffe87fe8000)
	libncursesw.so.6 => not found
	libgcc_s.so.1 => /gnu/store/vfvd0r69nv3221p907nb7cgk7inzmf9q-gcc-6.3.0-lib/lib/libgcc_s.so.1 (0x00007fd7fd492000)
	libc.so.6 => /gnu/store/iwgi9001dmmihrjg4rqhd6pa6788prjw-glibc-2.24/lib/libc.so.6 (0x00007fd7fd0f3000)
	/gnu/store/iwgi9001dmmihrjg4rqhd6pa6788prjw-glibc-2.24/lib/ld-linux-x86-64.so.2	(0x00007fd7fd6a9000)

$ ls ~/.guix-profile/lib/libncursesw.so.6
/home/<user>/.guix-profile/lib/libncursesw.so.6@

Set LD_LIBRARY_PATH=$HOME/.guix-profile/lib could solve this, but it is
said that is not a good solution.  So I think we need a solution to make
$HOME/.guix-profile/lib the fallback to search dynamic linked library.

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?

It works for me without any tricks. Make sure you are using
gcc-toolchain and not gcc package.

You can try the following command :

guix package -i gcc-toolchain -r gcc binutils glibc

Thanks a lot!  This does the trick!
