Subject: [PATCH] syscalls: Consistently use existing linux? definition

From: [email-masked]
Date: Thu, 3 Aug 2023 13:20:09 +0200

From: Sören Tempel <[email-masked]>

Instead of duplicating this existing logic across the source file. This
will make it easier to add additional linux targets (e.g. linux-musl) in
the future.

* guix/build/syscalls.scm (readdir*): Use linux? constant.
* guix/build/syscalls.scm (write-socket-address!): Use linux? constant.
* guix/build/syscalls.scm (read-socket-address): Use linux? constant.
