- Fix building on FreeBSD 7.x .
- Install GCC utilities needed by GPC (doesn't work if base system GCC isn't
the same as the one used to build GPC) .
- Don' change the default GCC installation directory hierarchy, but avoid
possible conflicts with other GCC compilers by prepending a "gpc" directory
