1 /*
2  * Dummy gnu/stubs.h. clang can end up including /usr/include/gnu/stubs.h when
3  * compiling BPF files although its content doesn't play any role. The file in
4  * turn includes stubs-64.h or stubs-32.h depending on whether __x86_64__ is
5  * defined. When compiling a BPF source, __x86_64__ isn't set and thus
6  * stubs-32.h is selected. However, the file is not there if the system doesn't
7  * have 32bit glibc devel package installed leading to a build failure.
8  *
9  * The problem is worked around by making this file available in the include
10  * search paths before the system one when building BPF.
