- Authentication-results: sourceware.org; auth=none
check-installed-headers tests were failing for x32 because of the x86
bits/sysctl.h containing a #error for x32. This patch makes the tests
ignore sys/sysctl.h for x32, similar to the other special-casing of
particular headers.
Tested for x86_64 (full testing for -m64, compile-only for x32).
