This patch adds a kbuild testcase to check whether kernel headers can be
correctly found.
For example:
# mv /lib/modules/4.3.0-rc5{,.bak}
# perf test LLVM
38: Test LLVM searching and compiling : Skip
# perf test -v LLVM
...
<stdin>:11:10: fatal error: 'uapi/linux/fs.h' file not found
#include <uapi/linux/fs.h>
^
1 error generated.
ERROR: unable to compile -
Hint: Check error message shown above.
Hint: You can also pre-compile it into .o using:
clang -target bpf -O2 -c -
with proper -I and -D options.
Failed to compile test case: 'Test kbuild searching'
test child finished with -2
