This is likely to require very non-trivial changes to gcc or clang.
The major issue is that the process needs to be in a known initial
state before beginning a compile - and it's very unlikely that the
compiler cleans itself up enough to return to that state.
If you really want to trim low-hanging fruit, try disposing of libtool
and GNU configure instead - their overheads are _many_ orders of
magnitude higher than make exec()ing gcc.
