This change reworks CPP_BUILTINS_SPEC for powerpc-vxworks to prepare for the upcoming addition of 32 and 64 bit ports for VxWorks 7r2.
This has been used in gcc-9 based production compilers for a
year on both vxworks 7 and 6.9. Also passed a build & test sequence
for powerpc-vxworks 7 and 6.9 with gcc-10 and a sanity check build
with a recent mainline.
Will commit to mainline shortly.
