determine compiler version at build time, not in configure

this makes it consistent with the determination of the default
include/library paths. this makes sense, as it's possible to switch the
sdk/toolchain after building qt (within reason).

a side effect of this change is that for compilers which emulate other
compilers, both the real and the emulated version are now made
available.
