build.sh's first step is to build the compiler suite in the source
tree and use *that* to build everything else. The compiler version in
the hosting system is irrelevent since it is only used for bootstrap...

Are those the versions of the compilers in the tool directories or the
versions in the hosting system?

Anyway, I've checked (since I didn't remember) and it appears that we
haven't gotten a compiler upgrade in some time -- in particular, 2.0
was released with the current compiler. That means that my hypothesis
is wrong. The performance drop from 1.6 to 2.0 was the compiler, but
this is likely something else.
