-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.
