-No need to wrap vdso calls as gentoo does not use any version of
-glibc <=2.3.3

-COMPAT_VDSO is inappropriate for any modern Hardened Gentoo system. It
-conflicts with various parts of PaX, crashing the system if enabled
-while PaX's NOEXEC or UDEREF features are active. Moreover, it prevents
-a number of important PaX options from appearing in the configuration
-menu, including all PaX NOEXEC implementations. Unfortunately, the
-reason for the disappearance of these PaX configuration options is
-often far from obvious to inexperienced users.
-Therefore, we disable the COMPAT_VDSO menu entry entirely. However,
-COMPAT_VDSO operation can still be enabled via bootparam and sysctl
-interfaces. Consequently, we must also disable the ability to select
-COMPAT_VDSO operation at boot or runtime. Here we patch the kernel so
-that selecting COMPAT_VDSO operation at boot/runtime has no effect if
-conflicting PaX options are enabled, leaving VDSO_ENABLED operation
-Closes bug:
