From 7b2a0cdc281d94a5782c37ef87040c341447b4b4 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Fri, 30 Apr 2021 10:35:02 +0100 Subject: [PATCH] libxcrypt: Update to 4.4.19 release and fix symbol version If you pass CFLAGS with a leading space, " " gets passed to popen and convinces gcc to try and open a file called " ". This results in a confusing error message like: x86_64-pokysdk-linux-gcc: error: : No such file or directory Avoid this by stripping empty elements out of CFLAGS.
