Historically, the base dir has been mostly about "your" code...
So not everything with the toolchain, whether it was -MD or -B,
was converted as the compiler was usually sitting still in /usr.
Lately there has been some changes to this (e.g. 60178b7), so
maybe there are more paths that _could_ be converted to relative.
But personally I would probably need to have *two* base paths,
for that to work (one for the source code, one for the toolchain)
So that I could have a base dir of $HOME/myproject but a toolchain
dir of e.g. /usr, just in case I wanted to relocate the toolchain.
Do you have some more examples, of where this is useful (to you) ?
