Subject: [PATCH] gnu: rapidcheck: Fix pkg-config libs.

From: Liliana Marie Prikler <[email-masked]>
Date: Fri, 20 Sep 2024 12:00:51 +0200

Using rapidcheck as a dependency in a project currently results in a linker
error, because the pkg-config file is missing relevant linker flags.

* gnu/packages/patches/rapidcheck-fix-libs.patch: New file.
* gnu/local.mk (dist_patch_DATA): Register it here.
* gnu/packages/check.scm (rapidcheck)[patches]: Use it here.

+Subject: [PATCH] Add -lrapidcheck to pkg-config module
+
+This adds the library to rapidcheck.pc, so that it doesn't have
+to be specified manually in projects that consume it.
+
+The other modules don't need it because they have rapidcheck in
+their Requires field.
