Doesn't build 32 bit vDSO for arm64

Hi Greg and Antonio,

The stable-rc 5.4 build is failing. ( 5.10 and 5.15 builds pass ) because new build getting these two extra configs.

CONFIG_GENERIC_COMPAT_VDSO=y CONFIG_COMPAT_VDSO=y

These two configs are getting added by extra build variable

CROSS_COMPILE_COMPAT=arm-linux-gnueabihf-

This extra variable is coming from new tuxmake tool.
