Subject: [PATCH 3/3] gnu: cross-base: Use cross-kernel-headers package in
cross-gcc and cross-libc.
* gnu/packages/cross-base.scm (cross-gcc): Add cross-kernel-headers procedure
which return the headers needed for each kernel. Replace "xlinux-headers"
input with "xkernel-headers" input.
(cross-libc): Add "xkernel-headers" package. Replace Hurd's cross-libc propagated
inputs with "kernel-headers".
