gnu: glibc: Refer to the target kernel headers when cross-compiling.
This fixes a regression introduced in efc4eb147512fa7a2c6d74d9b296cfc22b1ef198 whereby the build process corresponding to 'guix build glibc --target=mips64el-linux-gnu' would refer to the native headers instead of the target headers, leading to a build failure: ../sysdeps/unix/sysv/linux/statfs64.c: In function ‘__statfs64’: ../sysdeps/unix/sysv/linux/statfs64.c:73:1: error: control reaches end of non-void function [-Werror=return-type] } ^ When we were using CROSS_CPATH instead of CROSS_C_INCLUDE_PATH, the problem was hidden by the fact that CPATH corresponds to '-I' whereas C_INCLUDE_PATH corresponds to '-isystem', and '-isystem' directories are searched after '-I' directories. * gnu/packages/base.scm (glibc)[arguments]: Refer to the kernel headers from '%build-target-inputs' when cross-building.
