[bug#67257] [PATCH v2 1/2] gnu: Add nx-libs.

["Ludovic Courtès" <ludo@gnu.org>]

Hi!

Thank you Steve for shepherding this patch set!  Here are some comments
on minor issues.

The second line is unnecessary.

Please make sure to add the file to ‘gnu/local.mk’.

Looks like a couple of lines are missing from the usual header.

‘which’ returns ‘python3’ as found in $PATH—i.e., the native python.

To do the right thing in a cross-compilation context (for example, pick
the AArch64 ‘python3’ binary if you’re cross-compiling to AArch64), it
should be written like this:

  (lambda* (#:key inputs #:allow-other-keys)
    (substitute* …
      (… … (search-input-file inputs "/bin/python3"))))

Please describe that the package does; who maintains it is usually not
relevant here:
