[v2] selftests: vDSO: parse_vdso: Make compatible with nolibc

[PATCH v2 08/16] selftests: Add headers target

Posted by Thomas Weißschuh 9 months, 3 weeks ago

Some selftests need access to a full UAPI headers tree, for example when
building with nolibc which heavily relies on UAPI headers.
A reference to such a tree is available in the KHDR_INCLUDES variable,
but there is currently no way to populate such a tree automatically.

Provide a target that the tests can depend on to get access to usable
UAPI headers.
