Hello, This change replaces uses of CPU by uses of _VX_CPU in TARGET_OS_CPP_BUILTINS for arm-vxworks, as the latter form is more widely recognized across VxWorks versions.
It also adds a case for armv8, supported by at least
recent versions of VxWorks 7.
Tested in house with builds and various testsuite runs
for both gcc-8 and gcc-9 based toolchains. Also sanity-checked
that I could build a VxWorks toolchain with this change on top
of mainline sources, where the patch applies unchanged.
