Leo YanandGreg Kroah-Hartman 5e51bb7ffc perf python: split Clang options when invoking Popen 
[ Upstream commit c6a43bc3e8 ]

When passing a list to subprocess.Popen, each element maps to one argv
token. Current code bundles multiple Clang flags into a single element,
something like:

  cmd = ['clang',
         '--target=x86_64-linux-gnu -fintegrated-as -Wno-cast-function-type-mismatch',
	 'test-hello.c']

So Clang only sees one long, invalid option instead of separate flags,
as a result, the script cannot capture any log via PIPE.

Fix this by using shlex.split() to separate the string so each option
becomes its own argv element. The fixed list will be:

  cmd = ['clang',
         '--target=x86_64-linux-gnu',
	 '-fintegrated-as',
	 '-Wno-cast-function-type-mismatch',
	 'test-hello.c']

Fixes: 09e6f9f983 ("perf python: Fix splitting CC into compiler and options")
