Subject: [bug#50201] [PATCH 08/52] gnu: mozjs-60: Fix cross-compilation build errors.
Date: Wed, 25 Aug 2021 20:02:48 +0200

Presumably the other versions of mozjs need some changes
as well, but for now only fix mozjs <at> 60, which is a dependency
of polkit.

* gnu/packages/gnuzilla.scm
  (mozjs-60)[arguments]<#:configure-flags>: Set --with-nspr-prefix
  and set --host and --target inappropriately when cross-compiling.
  (mozjs-60)[arguments]<#:phases>{set-PKG_CONFIG}: New phase
  when cross-compiling.
