+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.
+
+Upstream-Status: Submitted [https://github.com/besser82/libxcrypt/pull/126]
