+Subject: [PATCH] build_support: fix cross-compilation error when CC is a
+ multi-part command
+
+Fix the following error when cross-compiling with an environment-defined CC
+that includes flags:
+
+FileNotFoundError: [Errno 2] No such file or directory: 'x86_64-wrs-linux-gcc
+-m64 -march=nehalem -mtune=generic -mfpmath=sse -msse4.2
+-fstack-protector-strong  -O2 -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security
+-Werror=format-security
+--sysroot=/build-1.3.0/tmp/work/corei7-64-wrs-linux/python3-posix-ipc/1.3.0/recipe-sysroot'
+
+This happened because the CC environment variable was treated as a single
+string instead of being split into arguments. The fix uses shlex.split() to
+correctly parse CC into a list of compiler and flags, and then unpacks it when
+forming the subprocess command.
+
+Upstream-Status: Backport [https://github.com/osvenskan/posix_ipc/commit/0113409]
