gcc searches an internal search patch before $PATH.  They say this can
be overridden with the -B option or the GCC_EXEC_PREFIX environment
var.

For once-off stuff I just get dirty and do `make V=1'.  Then copy and
paste the gcc command line and add `-v'.  Then copy, paste and edit the
various gcc subcommands.
