Well, sure!  My script at http://kegel.com/crosstool does this:
1) configure glibc and do 'make install-headers'; a wee bit of hackery
    circumvents its urge to build everything
2) build and install bootstrap compiler
3) build and install real glibc
4) build and install real gcc

My step #1 isn't pretty, but it only takes a couple minutes, and I'm
sure it's faster than what you described.  I thought you knew about
that already...
