From fda53f0791f5657d41735a40a29df3c8d0e8ae79 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 26 Jul 2022 18:39:49 +0200 Subject: [PATCH] package/Makefile.in: add detection for the lack of C library We recently had several cases of architecture configurations for which no C library was available, leading to a build failure during the gcc build. In order to more easily detect those bogus configurations, let's bail out very early by detecting the lack of C library selection.
