[PATCH v2 15/16] selftests: vDSO: vdso_test_gettimeofday: Make compatible with nolibc

Posted by Thomas Weißschuh 9 months, 3 weeks ago

nolibc does not provide sys/time.h and sys/auxv.h,
instead their definitions are available unconditionally.

Guard the includes so they are not attempted on nolibc.
