gnu: cross-base: Distinguish cross Linux headers from native headers.
Commit c6d33a9 provided an incorrect fix, whereby the "linux-headers" key would be used twice in %BUILD-INPUTS and the 'set-cross-path' phase would refer to the first one of them, which happened to be the native headers, and not the target headers. This patch solves the problem by removing the ambiguity. * gnu/packages/cross-base.scm (cross-gcc-arguments)[set-cross-path]: Remove to "xlinux-headers" instead of "linux-headers". (cross-gcc): When LIBC is true, add explicit "xlinux-headers" input, taken from LIBC's propagated inputs.
