in repository guix.

commit 5ee38c467298091e98fa12be45facdcc63a59a87
Author: Pierre Langlois <pierre.langlois@gmx.com>
AuthorDate: Wed Aug 11 16:43:45 2021 +0100

    gnu: node: Enable cross-compilation.
    
    Node runs parts of itself on the host for bootstraping therefore for
    cross-compiling support we need to fidle with the rpath in the build system,
    as well as duplicating some of the dependencies as native-inputs and inputs.
    
    * gnu/pakcages/node.scm (node)[arguments]: Refer to /bin/sh and /bin/env
    directly instead of using (which).  Add new 'set-bootstrap-host-rpath phase
    to correctly set the rpath for binaries that are meant to run on the host.
    Pass --cross-compiling and --dest-cpu to configure script if needed.  Set 
the
    CC_host, CXX_host, CC, CCX and PKG_CONFIG variable for cross-compilation.
    Refer to the host python.  Do not return #t from any phases.
    [native-inputs]: Add c-ares, http-parser, icu4c, libuv, nghttp2, openssl and
    zlib.  Remove which.
    [inputs]: Add bash and coreutils.
    (llhttp-bootstrap)[arguments]: Refer to esbuild via (or native-inputs 
inputs).
    (node-lts)[arguments]: Add new 'set-bootstrap-host-rpath phase to correctly
    set the rpath for host binaries.  Pass --cross-compiling and --dest-cpu to
    configure script if needed.  Set the CC_host, CXX_host, CCX and PKG_CONFIG
    variable for cross-compilation.  Refer to the host python.  Do not return #t
    from any phases.  Refer to /bin/sh and /bin/env directly instead of
    using (which).  Do not return #t from any phases.
    [native-inputs]: Hardcode native inputs instead of inheriting them from 
node.
    [inputs]: Add bash and coreutils.
