;; The 'target' field must be a valid GNU triplet as defined here:
|
||
;; https://www.gnu.org/software/autoconf/manual/autoconf-2.68/html_node/Specifying-Target-Triplets.html.
|
||
;; It is used for cross-compilation purposes.
|
||
;;
|
||
;; The 'system' field is the name of the corresponding system as defined in
|
||
;; the (gnu packages bootstrap) module. It can be for instance
|
||
;; "aarch64-linux" or "armhf-linux". It is used to emulate a different host
|
||
;; architecture, for instance i686-linux on x86_64-linux-gnu, or armhf-linux
|
||
;; on x86_64-linux, using the QEMU binfmt transparent emulation mechanism.
|
||
;;
|
||
;; The 'linux-architecture' is only relevant if the kernel is Linux. In that
|
||
;; case, it corresponds to the ARCH variable used when building Linux.
|
||
;;
|
||
;; The 'glibc-dynamic-linker' field is the name of Glibc's dynamic linker for
|
||
;; the corresponding system.
