[bug#36477] [PATCH v3 23/48] gnu: make-linux-libre: Fix cross-compilation.

[Mathieu Othacehe]

* gnu/packages/linux.scm (make-linux-libre)[arguments]: Unset CROSS_CPATH to
make sure that cross-libc is not found. Otherwise, some of its header would
conflict with the one from linux (stdint.h and linux/types.h).
